A pilot was killed when his amateur-built high-powered Pitts S2 aerobatic biplane crashed into a paddock next to the Pallamana Aerodrome at Murry Bridge in South OZ



The 33-year-old pilot - Rob Morgan - was performing aerobatics at the time and failed to recover from a vertical dive at the end of a manoeuvre



Post crash image indicates the engine was at a low power setting and may have failed to respond at a crucial time during the aerobatic recovery sequence

A 50-year-old pilot and his 51-year-old passenger escaped serious injury yesterday when the vintage De Havilland Chipmunk aircraft they were in experienced an engine problem and crashed shortly after take-off from Goulburn Airport in NSW



"Both occupants were reported as being in a stable condition yesterday afternoon at Goulburn Base Hospital with minor injuries"

Two people have died when a World-War-2 era Tiger Moth they were in collided with trees when departing Maryborough Airport located around 170 kms north-west of Melbourne



The 2-seat DH-82 vintage bi-plane clipped the trees shortly after take-off and then impacted the ground and burst into flames just after 1700hrs to-day - there were no survivors

Theory of Flight textbooks up to now have always explained that lift occurs because of the pressure change of the air mass passing over the curved upper surface of the wing has further to travel than underneath meaning it must travel faster and in doing so creates a low-pressure 'lift' zone that assumes the split airflows will arrive at the trailing edge of the wing at the same time



Professor Babinsky explains - "although lift is caused by a pressure change between the top and bottom surfaces - it's due to the change in the shape of the air flow rather than its speed"
