Amelia Earhart's sad demise

Dozens heard Amelia Earhart's final, chilling pleas for help, researchers say



Distilled from 2 posts in the  Washington Post and the Web

Amelia Earhart waded into the Pacific Ocean and climbed into her downed and disabled Lockheed Electra. The famous aviator started the engine, turned on the two-way radio and sent out a plea for help, one more desperate than previous messages.



The high tide was getting higher, she had realised. Soon it would suck the plane into deeper water, cutting Earhart off from civilisation - and any chance of rescue.



Aviator Amelia Earhart's cries for help were heard by people who just happened to be listening to their radios at the right time.
Across the world, a 15-year-old girl listening to the radio in St Petersburg, Florida transcribed some of the desperate phrases she heard: "waters high," "water's knee deep - let me out" and "help us quick."
A  housewife in Toronto heard a shorter message, but it was no less dire: "We have taken in water . . . we can't hold on much longer."


On July 2, 1937, just after Earhart's plane disappeared, the US Navy put out an "all ships, all stations" bulletin.

That harrowing scene, the International Group for Historic Aircraft Recovery (TIGHAR) believes, was probably one of the final moments of Earhart's life. The group put forth the theory in a paper that analyses radio distress calls heard in the days after Earhart disappeared.

In the summer of 1937, she had sought to become the first woman to circumnavigate the globe. Instead, TIGHAR's theory holds, she ended up marooned on a desert island, radioing for help.


Earhart and her navigator, Fred Noonan, could only call for help when the tide was so low it wouldn't flood the engine, TIGHAR theorised. That limited their pleas for help to a few hours each night.


It wasn't enough, TIGHAR director Ric Gillespie told The Washington Post, and the pair died as castaways.

But those radio messages form a historical record - evidence that Gillespie says runs counter to the US Navy's official conclusion that Earhart and Noonan died shortly after crashing into the Pacific Ocean.

"These active versus silent periods and the fact that the message changes on July 5 and starts being worried about water and then is consistently worried about water after that - there's a story there," Gillespie said.

"We're feeding it to the public in bite-sized chunks. I'm hoping that people will smack their foreheads like I did."

Some of Earhart's final messages were heard by members of the military and others looking for Earhart, Gillespie said.


Others caught the attention of people who just happened to be listening to their radios when they stumbled across random pleas for help.


Almost all of those messages were discounted by the US Navy, which concluded that Earhart's plane went down somewhere in the Pacific Ocean, then sank to the seabed.






Gillespie has been trying to debunk that finding for three decades. He believes that Earhart spent her final days on then-uninhabited Gardner Island.

She may have been injured, Noonan was probably worse, but the crash wasn't the end of them.

On July 2, 1937, just after Earhart's plane disappeared, the US Navy put out an "all ships, all stations" bulletin, TIGHAR wrote.Authorities asked anyone with a radio and a trained ear to listen in to the frequencies she had been using on her trip, 3105 and 6210 kilohertz.

It was not an easy task. The Electra's radio was designed to communicate only within a few hundred kilometres. The Pacific Ocean is much bigger. The searchers listening to Earhart's frequencies heard a carrier wave, which indicated that someone was speaking, but most heard nothing more than that.

Others heard what they interpreted to be a crude attempt at Morse code.But thanks to the scientific principle of harmonics, TIGHAR says, others heard much more.

In addition to the primary frequencies, "the transmitter also put out 'harmonics (multiples)' of those wavelengths," the paper says. "High harmonic frequencies 'skip' off the ionosphere and can carry great distances, but clear reception is unpredictable."

That means Earhart's cries for help were heard by people who just happened to be listening to their radios at the right time.

According to TIGHAR's paper:

"Scattered across North America and unknown to each other, each listener was astonished to suddenly hear Amelia Earhart pleading for help. They alerted family members, local authorities or local newspapers. Some were investigated by government authorities and found to be believable. Others were dismissed at the time and only recognised many years later.



Although few in number, the harmonic receptions provide an important glimpse into the desperate scene that played out on the reef at Gardner Island."

The tide probably forced Earhart and Noonan to hold to a schedule. Seek shelter, shade and food during the sweltering day, then venture out to the craft at low tide, to try the radio again.

Back in the United States, people heard things, tidbits that pointed at trouble.

On July 3, for example, Nina Paxton, an Ashland, Kentucky, woman, said she heard Earhart say "KHAQQ calling," and say she was "on or near little island at a point near" . . . "then she said something about a storm and that the wind was blowing....Will (or We'll ) have to get out of here," she says at one point. "We can't stay here long."

What happened to Earhart after that has vexed the world for nearly 81 years, and TIGHAR is not the only group to try to explain the mystery. Gillespie is just one member of competing researchers who have dedicated their time and resources to one of aviation's greatest mysteries.

Mike Campbell, a retired journalist who wrote Amelia Earhart: The Truth at Last, insists along with others that Earhart and Noonan were captured in the Marshall Islands by the Japanese, who thought they were American spies, and died in Japanese custody after being tortured.

Elgen Long, a Navy combat veteran and an expert on Earhart's disappearance, wrote a book saying her plane crashed into the Pacific and sank.

Gillespie said he believes that evidence supporting his Gardner Island theory is adding up.


He believes that the messages sent out over those six days were by Earhart and, occasionally, Noonan. He believes that bones found on Gardner island in 1940 belonged to Earhart, but were misidentified and discarded.

He believes that Amelia Earhart died marooned on an island after her plane was sucked into the Pacific Ocean. But he realises that the public needs more than his tide tables and extrapolations from data that predates World War II.

"We're up against a public that wants a smoking gun," he told The Post.

"We know the public wants, demands, something simple. And we're also very much aware that we live in a time of rampant science denial. Nobody does nuance anymore."


Bones discovered on a Pacific island in Kiribati 'belong to Amelia Earhart'



Amelia Earhart's story is revolutionary: She was the first woman to fly alone across the Atlantic Ocean, and might have been the first to fly around the world had her plane not vanished over the Pacific Ocean in 1937. After decades of mystery surrounding her disappearance, her story might come to a close.


A scientific study claims that bones found in 1940 on the Pacific Island of Nikumaroro belong to Earhart, despite a forensic analysis of the remains conducted in 1941 that linked the bones to a male.
The bones, revisited in the study Amelia Earhart and the Nikumaroro Bones by University of Tennessee professor Richard Jantz, were discarded. For decades they have remained an enigma, as some have speculated that Earhart died a castaway on the island after her plane crashed.

Nikumaroro, or Gardner Island, is part of the Phoenix Islands, Kiribati in the western Pacific Ocean.


The bones were uncovered by a British expedition exploring the island for settlement after they came upon a human skull, according to the study. The expedition's officer ordered a more thorough search of the area, which resulted in the discovery of several other bones and part of what appeared to be a woman's shoe. Other items found included a box made to hold a Brandis Navy Surveying Sextant that had been manufactured around 1918 and a bottle of Benedictine, an herbal liqueur.
"There was suspicion at the time that the bones could be the remains of Amelia Earhart," Jantaz wrote in the study.

When the 13 bones were shipped to Fiji and studied by Dr D W Hoodless of the Central Medical School the following year, Jantz argues that it is likely that forensic osteology - the study of bones - was still in its early stages, which therefore affected his assessment of which sex the remains belonged to. Jantz, in attempting to compare the lost bones with Earhart's bones, co-developed a computer program that estimated sex and ancestry using skeletal measurements. The program, Fordisc, is commonly used by forensic anthropologists across the globe.

Jantz compared the lengths of the bones to Earhart's measurements, using her height, weight, body build, limb lengths and proportions, based on photographs and information found on her pilot's and driver's licenses. His findings revealed that Earhart's bones were "more similar to the Nikumaroro bones than 99  of individuals in a large reference sample."

"In the case of the Nikumaroro bones, the only documented person to whom they may belong is Amelia Earhart," Jantz wrote in the study.

Earhart's disappearance has long captivated the public, and theories involving her landing on Nikumaroro have emerged in recent years. Retired journalist Mike Campbell, who authored Amelia Earhart: The Truth at Last, has maintained with others that Earhart and her navigator, Fred Noonan, were captured in the Marshall Islands by the Japanese, who thought they were American spies. He believes they were tortured and died in custody.

But Ric Gillespie, director of the International Group for Historic Aircraft Recovery (TIGHAR) spoke to The Washington Post's Cleve R. Wootson Jr. in 2016 about how he too believes the bones found on Nikumaroro belong to Earhart.


In 1998, the group took Hoodless' measurements of the Nikumaroro bones and analysed them through a robust anthropological database. They determined the bones belonged to a taller-than-average woman of European descent - perhaps Earhart, who at 5 feet 7 (170cm) to 5 feet 8 (172.7cm), was several inches taller than the average woman.

In 2016, the group brought the measurements to Jeff Glickman, a forensic examiner, who located a photo of Earhart from Lockheed Aircraft that showed her with her arms exposed. It appeared, based on educated guesses, that Earhart's upper arm bone corresponded with one of the Nikumaroro bones.

Glickman, who is now a member of TIGHAR, told The Washington Post at the time that he understands some might be skeptical about his findings, as they were based 76-year-old medical notes. But the research made clear, he said, that Earhart died on Nikumaroro.

RNZAF P3 Orion Joins search for Malaysia Aircraft

RNZAF Joins search for Malaysian Aircraft

A New Zealand Air Force P3 - K Orion is joining the international effort to find a missing Malaysia Airlines Boeing 777 lost over the South China Sea.

The maritime surveillance aircraft left Auckland last night and is now heading to Butterworth near Penang in Malaysia.
Prime Minister John Key said it would work with two Australian Orions and search the sea north of Malaysia.
"Much remains unclear about what has happened to the flight," he said.
"New Zealand wants to do its part in the search and rescue effort to locate the aircraft.
"While we are aware the hope for positive news is fading, our thoughts remain with the family members of those who were on the flight, particularly the families of New Zealanders Paul Weeks and Ximin Wang."
Meanwhile Auckland International Airport said it had increased security checks around the daily Malaysian Airlines' flights.
A spokesman said the airline ordered extra security for their passengers.
It includes an additional screening of all passengers after check-in and just prior to boarding.
It is one step up on the procedures adopted for flights to the United States which involves only random screening at the boarding gate.
An airport spokesman said the new checks had not caused any delays or additional time for passengers.
The Royal New Zealand Air Force (RNZAF) has accepted the first of six upgraded P-3K2 Orion maritime patrol aircraft into service with No 5 Squadron. 
I suspect making this aircraft available is also a test of its operational capability: 
The RNZAF operates 6 Orions, upgraded to the K2 standard: 

Formal Introduction into service ceremony was conducted at Whenuapai Air Force Base in Auckland on 2 May 2011.

Orion NZ 4204 (the prototype P-3K2) returned to New Zealand in late April 2011, after being in Texas, United States, since 2005 for the P-3 Mission Systems Upgrade Project. The project will see all six New Zealand Orions re-equipped with an airborne surveillance and Response Capability. According to the chief of the air force Air Vice-Marshal Peter Stockwell, this capability is “up with the very best”.

The scope of this project includes the replacement of the data management system, sensors, communications and navigation systems, and the provision of associated ground systems.

According to the RNZAF, the upgraded P-3K2 Orion introduced a fundamental change to the operation of the Orions as they transition from a Maritime Patrol Force to an airborne Surveillance and Response Force. This change is significant because the focus of the operations will include overland operations as well as traditional maritime operations.

The production phase of the project saw the five remaining Orions cycle through Safe Air’s facilities at Blenheim, New Zealand, to be stripped internally, re-wired and re-equipped with new mission systems.

Orion NZ 4201 was in Blenheim at the time, and the upgrade of that aircraft was well advanced. At the rate of about one every six months, by 2014 the RNZAF will have a fleet of six P-3K2 Orions all newly equipped with 21st century surveillance and communications systems, the RNZAF says.

Air Vice-Marshal Peter Stockwell foresees a very exciting time for the RNZAF, as operational testing and evaluation begins. “Our goal now is the delivery of the capability as rapidly as possible. I believe our P-3K2 Orions will be better equipped than ever to support Defence Force operations world-wide and other government agencies closer to home.”

The project’s origins lay with the 2001 Maritime Patrol Review. At that time the P-3s had a mix of 1960s and 1980s equipment. Built new as P-3Bs in 1966 (New Zealand was then was the first country outside of the USA to operate Orions), the fleet had already been modernised in 1982 under Project Rigel, which saw some of the mission systems replaced and upgraded.

In 2000, Project Kestrel saw the fleet structurally renewed to extend their life. But the aircrafts’ tactical capability was limited, and affected by hard-to-support older systems. As well, international air traffic control standards were changing and there was the continual need to remain interoperable with New Zealand’s partners, particularly Australia.

In October 2004 the Crown signed a contract with L-3 Communications Integrated Systems to upgrade the aircraft at a cost of NZ$373 million.

The aircraft had been due to return to New Zealand in late 2008, but the programme encountered delays due to concerns over stall performance, issues with its digital indicated airspeed display during take-offs and a periodic yaw problem. Furthermore, the prototype was not allowed to fly for six months last year after loose fasteners were discovered on its wing straps, Flight International reports.

Under the original plans, work on all six aircraft was to have been completed by September 2010. 


Following its arrival back in New Zealand the prototype aircraft underwent a period of scheduled Depot Level Maintenance (DLM) before returning to 5 Squadron at RNZAF Base Auckland in September 2011. In Blenheim, the first production airframe, NZ4201, commenced its modification with SAL in June 2009 and was delivered back to the Crown in March 2012. The second production aircraft, NZ4205, joined the programme with SAL in April 2011 and was delivered to the Crown in September 2012. The third production aircraft, NZ4203, inducted into upgrade in March 2012, was delivered to the Crown in May 2013. The four delivered upgraded aircraft (NZ4201, NZ4203, NZ4204 and NZ4205) are based at RNZAF Base Auckland on 5 Squadron. 

Initially these airframes were utilised to conduct Operational Testing and Evaluation (OT&E) and ground and aircrew training. In the second quarter of 2012 the first of two P-3K2 transition courses commenced to train the P-3K aircrews onto the P-3K2. Transition training of all No. 5 Squadron air and ground crews is now complete and following the achievement of operational and technical airworthiness requirements, a release of an initial operational capability was declared in the first quarter of 2013. This initial capability focuses on Search and Rescue response and surveillance of New Zealand’s EEZ and territorial waters.

New Zealand industry participation was always intended for the project and Safe Air of Blenheim is the key sub-contractor in the production phase. Modifications were made to the P-3’s communications, navigation, surveillance, flight planning and data management systems while the flight deck was improved.

The RNZAF is also upgrading its five C-130 Hercules transports. A contract was signed with with L3 Communications to complete the air force's C130 life extension program. The latter includes the refurbishment of the aircrafts' centre wings, refurbishment or replacement of other structural components, a major rewire, replacement of avionics systems, flight management, autopilot and navigation and communication suites. This will ensure that the aircraft continue to comply with evolving air traffic control regulations worldwide.

The Royal New Zealand Air Force welcomed the return of the first of its modernised C-130s in 2010 last year. 


No. 40 Squadron who operates the C-130s, will be able to utilise the aircraft in the many roles undertaken for the government and New Zealand, including tactical air transport, disaster relief and civil defence support, aeromedical transport and support to the New Zealand Antarctic program.

The RNZAF also recently unveiled the first of its new Agusta Westland A109 LUH Light Utility Helicopters.

The new helicopters represent the start of a significant leap in technology for the Air Force's Rotary Wing. "The three helicopters are the first of five A109LUH to replace the Bell 47 Sioux,” he said. "The A109LUH is part of a Defence Force helicopter training system that includes computer based training, a procedural trainer and simulator. This provides a cost effective means of training aircrew prior to operational conversion onto the NH90 or SH2G helicopters.”

Five A109s were ordered in 2008 and are scheduled to be in service before the end of the year. The government announced last year it was ordering another three. The new A109s will be used for training, light utility tasks in support of the other services and government agencies.

Turbulence ahead: Global warming to increase the bumpy rides

Turbulence ahead



Is global warming gonna give us a bumpy ride?

Fairfax News Reports: New research has found global warming is likely to double the chances of plane turbulence in the coming decades.
According to a study from the University of Reading and the University of East Anglia, atmospheric changes could lead to the amount of turbulent air patterns that affect planes doubling, and for the intensity to get stronger by the middle of this century.
Dr Paul Williams, who headed the research, said global warming would have a significant impact on the aviation industry.
"Air turbulence does more than just interrupt the service of in-flight drinks. It injures hundreds of passengers and aircrew every year - sometimes fatally.
"It also causes delays and damages planes. The total cost to society is about US$150 million (NZ$177 million) each year."
Researchers used supercomputer simulations to analyse jet streams over the North Atlantic Ocean.
Dr Manoj Joshi, from East Anglia, said they focused on looking at turbulence in its peak periods.
"Our research focused on clear-air turbulence in winter. This is especially problematic to airliners, because clear-air turbulence is invisible to pilots and satellites, and winter is when it peaks."
It found the chances of encountering significant turbulence would increase by between 40 per cent and 170 per cent, but most likely double, and the intensity by anywhere between 10 and 40 per cent.
Williams said any increase in turbulence would make flying more uncomfortable and increase the risk to passengers and crew.

He said airlines would also be forced to re-rout some flights to avoid stronger patches of turbulence, which would lead to greater fuel consumption and emissions of atmospheric pollutants, make delays at airports more common, and ultimately push up ticket prices.
The research showed the atmosphere was becoming more vulnerable and unstable, and Williams said the aviation industry was partly to blame for that.

NZ Perspective: I hold appointment to the Civil Aviation Authority of NZ as Departmental Medical Practitioner. (Health and Safety) All NZ registered flights and flight crews report significant injuries to the CAA. I am not aware of any fatalities of crew and passengers attributable to air turbulence. The last attributable commercial air crash worldwide was in 1966:


Commercial air traffic, in terms of turbulence, is pretty darn safe
The last crash caused by turbulence was  in 1966 near Mount Fuji in Japan.

In 2010, the US National Highway Traffic Safety Administration reported 9,442,000 car accidents, including more than 22,000 fatalities and almost 2 million injuries. The same year, the National Transportation Safety Board (NTSB) documented one major accident and 14 injuries on commercial planes, and no fatalities.

But don't be so quick to unbuckle your seat belt and freely roam the cabin. Turbulence is the No. 1 cause of in-flight injuries, with crew members often suffering the highest number of bangs, bruises and broken bones. The FAA reported that turbulence injured five passengers and 28 crew members last year. Over the same period, the NTSB investigated 10 turbulence-related accidents.

If people followed the rules the statistics would be even lower: Protecting yourself is as easy as insert, click, adjust. Even when the pilot turns off the sign, keep your seat belt on. If the plane suddenly jolts, you don't want to bump heads with the ceiling.
