Happy Birthday DH 98 Mosquito !

Seventy-four years ago today, the de Havilland DH.98 Mosquito took flight for the first time.

One of the most useful Allied aircraft of World War II, the Mosquito performed as a bomber, fighter, anti-shipping and photo-reconnaissance platform.  The key to the success of the “Wooden Wonder” was its light wood construction and the power of its twin Merlin engines, which gave it the speed to out-fly almost every other aircraft type of the war.  Nicknamed the “Mossie” by its crews, the Mosquito could fly virtually unchallenged and deliver devastatingly precise attacks with bombing radar.

Production of all Mosquitoes totaled 7,781 and the DH.98 served with over a dozen nations.  A Mosquito became the first twin-engine aircraft to land on a ship on March 25, 1944, aboard the Royal Navy aircraft carrier HMS Indefatigable.

Here is a photo of the DH.98 Mosquito from the Military Aviation Museum in Virginia Beach, Virginia taking-off during the 2013 Flying PROMS airshow.

This Mosquito was built in Canada in 1945 but never saw combat during the war.  The Military Aviation Museum acquired the aircraft in 2004 and it was shipped to New Zealand to undergo an eight-year restoration.  The restored aircraft made its first flight  (clicky) here in New Zealand in September 2012 and arrived back at the Military Aviation Museum in March 2013.  It is painted as EG-Y to replicate the No. 487 (NZ) Squadron of the Royal New Zealand Air Force as a tribute to those responsible for the restoration.

Wiki: The de Havilland DH.98 Mosquito was a British multi-role combat aircraft with a two-man crew that served during and after the Second World War. It was one of few operational front-line aircraft of the era constructed almost entirely of wood and was nicknamed "The Wooden Wonder".

 The Mosquito was also known affectionately as the "Mossie" to its crews. Originally conceived as an unarmed fast bomber, the Mosquito was adapted to roles including low to medium-altitude daytime tactical bomber, high-altitude night bomber, pathfinder, day or night fighter, fighter-bomber, intruder, maritime strike aircraft, and fast photo-reconnaissance aircraft. It was also used by the British Overseas Airways Corporation (BOAC) as a fast transport to carry small high-value cargoes to, and from, neutral countries, through enemy-controlled airspace.

When the Mosquito began production in 1941, it was one of the fastest operational aircraft in the world. Entering widespread service in 1942, the Mosquito was a high-speed, high-altitude photo-reconnaissance aircraft, continuing in this role throughout the war. From mid-1942 to mid-1943 Mosquito bombers flew high-speed, medium or low-altitude missions against factories, railways and other pinpoint targets in Germany and German-occupied Europe. From late 1943, Mosquito bombers were formed into the Light Night Strike Force and used as pathfinders for RAF Bomber Command's heavy-bomber raids. They were also used as "nuisance" bombers, often dropping Blockbuster bombs - 4,000 lb (1,812 kg) "cookies" - in high-altitude, high-speed raids that German night fighters were almost powerless to intercept.

As a night fighter, from mid-1942, the Mosquito intercepted Luftwaffe raids on the United Kingdom, notably defeating Operation Steinbock in 1944. Starting in July 1942, Mosquito night-fighter units raided Luftwaffe airfields. As part of 100 Group, it was a night fighter and intruder supporting RAF Bomber Command's heavy bombers and reduced bomber losses during 1944 and 1945.

 As a fighter-bomber in the Second Tactical Air Force, the Mosquito took part in "special raids", such as the attack on Amiens Prison in early 1944, and in precision attacks against Gestapo or German intelligence and security forces. Second Tactical Air Force Mosquitos supported the British Army during the 1944 Normandy Campaign. From 1943 Mosquitos with RAF Coastal Command strike squadrons attacked Kriegsmarine U-boats (particularly in the 1943 Bay of Biscay, where significant numbers were sunk or damaged) and intercepting transport ship concentrations.

The Mosquito flew with the Royal Air Force (RAF) and other air forces in the European, Mediterranean and Italian theatres. The Mosquito was also operated by the RAF in the South East Asian theatre, and by the Royal Australian Air Force (RAAF) based in the Halmaheras and Borneo during the Pacific War.

20 Injured in SAA Turbulence incident: Global warming causing worse turbulence

Turbulence incident: Global warming causing worse turbulence ? 

Severe turbulence struck a South African Airways plane that was heading to Hong Kong, injuring 20 people before the aircraft landed safely on Wednesday, the airline said.
Medics were waiting at the Hong Kong airport to assist passengers on SA286, which had departed Johannesburg on Tuesday, the airline said in a statement.
Television footage showed rescue workers wheeling one injured passenger on a stretcher.
Three crewmembers and 17 passengers were injured, airline spokesman Tlali Tlali said.
The Hong Kong fire department said two people were critically injured. The victims were taken to three hospitals.
SAA Airbus 340-300
The airline said 165 passengers were on the Airbus 340-300 when the turbulence hit the aircraft as it flew over Kuala Lumpur, the Malaysian capital
Last year in a similar incident about two dozen people on two flights were injured when their aircraft hit turbulence before landing at Hong Kong's airport.
Thai Airways said 20 people were hurt when an Airbus A38-800 carrying 500 passengers, two pilots and 24 cabin crew from Bangkok encountered "unforeseen turbulence" as it was descending to Hong Kong's airport.
The airline said passengers and cabin crew suffered injuries but the plane landed safely. 39 were reported injured but the airline later revised the number to 20. Kung says the injured were sent to three hospitals in the southern Chinese city.
Hong Kong Airlines reported three passengers and three flight attendants were hurt when their flight from Phuket hit "sudden turbulence" as it neared the city's airport. The airline said the plane landed safely and the six have left hospital. The plane was carrying 110 passengers and seven crew.
Clear air turbulence:
The most insidious kind of turbulence, clear-air turbulence, is invisible, comes without warning and occurs any time during a flight. One of the main culprits of clear-air turbulence is the boundary between the jet stream—that aerial river that forms where arctic air masses meet warmer air from the south—and the slower-moving air adjacent to it. This invisible boundary shifts unpredictably, and woe to any unstrapped passenger in a jet that crosses it. "If you're flying in clear air, you have no indication at all. If an aircraft has passed through the area ahead of your airplane, your pilot might get an advance warning of turbulence ahead. "But if you're an early morning flight and you're going through an area first, you're going to be 'Probe One.'" 
Even the worst turbulence is no cause for alarm—by itself. I don't think an airplane has ever broken up in flight because of turbulence. All planes are built to withstand much more than even a severe turbulent event."
Which makes passenger safety when an airplane hits turbulence—especially without warning—primarily the responsibility of the passengers themselves. That means buckling your seat belt, just as the pilots and stewardesses recommend, anytime you're seated. Air travelers should not get complacent. The best thing to do is to not loiter around in the aisles of the airplane," he says. "Do what you need to do, then get back to your seat and put on your seatbelt. You're still hurdling through the air at 500 miles an hour; things can happen. in 2005 an Air Korea jet fell 100 m in clear air turbulence, causing significant injury. Passengers and objects effectively become airborne, and go into free-fall until they hit something.

There has also been an unprecedented increase in turbulence involving aircraft in Australia.
The Australian Transport Safety Bureau said turbulence doubled over the three-month period between October to December 2013, compared to the previous three months, significantly above the five year historical average.
Turbulence is the leading cause of in-flight injuries and an increase directly affects the safety of cabin passengers.
But the ATSB could not speculate as to why it was happening, according to Dr Stuart Godley head of the ATSB's Aviation Research Team.
"During the last five years there has been an increase in reporting, particularly from cabin crew, about an increase in turbulence, but we don't know why this is occurring," he said.
"Because they are weather-related, these events are cyclical.
"We're used to seeing more of them in summer, but this increase is unprecedented."
Turbulence is caused by the irregular movement of air and often cannot be seen.
When air masses with different speeds, direction or temperatures meet each other, turbulence is likely to occur.
While turbulence is normal and occurs frequently, it can be dangerous - especially for passengers not wearing seat belts or carrying unsecured items.
That was the case for one passenger in November 2013 who sustained a serious head injury from a laptop computer that fell from an overhead locker during a turbulent flight to Sydney.
Another passenger was injured after being struck by an iPad. Passengers not wearing seat belts are more likely to be seriously injured when turbulence hits.
"Serious head injuries can be sustained when a person hits the overhead panel where luggage is stored because they did not wear a seat belt," he said.
"Cabin crew have had legs broken from walking around the cabin when turbulence hit," he said.
Clear air turbulence (CAT) can pose a great amount of danger as it cannot be detected and hit any time, which is exactly what happened when cabin crew were commencing a meal service during a flight from Cairns to Tokyo in 1996.
Passengers, crew and meal trolleys hit the ceiling of the aircraft and landed heavily, seriously injuring passengers who were not belted up. Bone fractures, lacerations, neck and back strains, dislocated shoulders and shattered teeth were reported. Four were admitted to hospital.
While nothing that extreme has been reported during the recent bout of increased turbulence, Godley warns passengers to keep their seat belts on in the off-chance it should happen. Some areas of Australia are more prone to turbulence and Sydney has been a common spot for it to occur over the last summer, Godley said. "122 incidences of turbulence were recorded, 35 of which occurred on flights in to and out of Sydney, which seems to be a hot-spot for turbulence," he said. "Brisbane and the Gold Coast is another area which experiences a high amount."

Global warming to blame?
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. 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.

Boeing P-26 Pea Shooter and Strange planes and Oddities

Gallery of the Bizarre: Odd looking aircraft: P-26 Pea Shooter



(photo: Michael O’Leary via Planes Of Fame)

The Planes of Fame Air Museum in Chino, California is sending their Boeing P-26A Peashooter to England this July to take part in the Flying Legends air show over the weekend of July 12th/13th at Duxford, in Cambridgeshire. This ulra-rare fighter plane is one of only two originals in existence, and the only one flying.

Interestingly, the Peashooter was the world’s first all-metal fighter, and the first monoplane in the US Army Air Corps. Boeing built 151 of them between 1932 to 1936. The type first saw combat with the Chinese Air Force on August 15th 1937, when eight Peashooter’s engaged twenty Japanese “Claude” bombers. They shot down two bombers without loss. A handful of them were still flying with the Army Air Corps in the Philippines when the US entered WWII in December, 1941. Ed Maloney acquired this example, 33-123, from the Guatemalan Air Force in 1957. The Guatemalan’s had used the type from 1943 until its retirement in 1957. The only other original survivor, P-26A 33-135, is on display with the Smithsonian’s National Air & Space Museum at their Udvar-Hazy Center in Chantilly, Virginia. They also acquired it from Guatemala in 1957. There are a half dozen faithful replicas in various stages of completion dotted around the USA at present, and although one of these has flown in recent years, none are currently active.

It is probably the first time that a P-26 has ever visited Europe, and it is bound to cause a stir at Flying Legends. The Fighter Collection, organizers of the hugely popular air show, based at Duxford have close ties to many of the established vintage aircraft collectors/collections in the USA. They often work to bring one of their more unusual overseas exhibits to be a part of the Flying Legends air show to keep it fresh each year. Flying Legends will be the only chance to see the Peashooter flying during her UK visit. According to the air show details, the Peashooter will fly a carefully scripted solo routine each day of the show, and sit on the Flight Line during the remainder to allow close viewing of the unusual monoplane.

N9MB_w_brdr

The Northrop N-9M was an approximate one-third scale, 60-ft wide, all-wing aircraft used for the development of the 172-ft wide Northrop XB-35 and YB-35 flying wing long-range, heavy bomber program. First flown in 1942, the N-9M (M for Model) was the third in a lineage of all-wing Northrop aircraft designs that began in 1929 when Jack Northrop succeeded in early experiments with his single pusher propeller, twin-tailed, twin-boom, all stressed metal skin Northrop Flying Wing X-216H monoplane, and a decade later, the dual-prop N-1M of 1939–1941. Northrop's pioneering all-wing aircraft would lead Northrop-Grumman many years later to eventually develop the advanced B-2 Spirit stealth bomber, which debuted in Air Force Inventory in 1989.
