Here's the update:
A friend of mine, Andrew, was taking off 06 at YKAT at around 5pm yesterday, in his recently purchased SuperCat (single seat, two stroke).
At about 100-150 feet the engine has failed, and the aircraft has crashed in scrub about 100 metres from the end of the runway (24 end).
It took about 45 minutes to find him. Rescue helicopter flew him to Nepean Hospital.
He has severe head injuries. Initial surgery last night lasted 5 hours, and they put him in an induced coma, which he is still in now.
Although the injuries are very bad, and he will be in hospital and rehab for months, at least he is alive.
Further updates as they come to hand.
