Just auditing some old memories. Anyone still around to remember the morning Dennis stormed about Goroka looking for a Qantas cadet -"I'll kill him". Said cadet had pulled thru the prop on a 296 in spite of standing instructions not to. A dud magneto switch combined with all the levers being forward from unloading pax from right front seat produced instant full power. Cadet dodged the prop and the 206 raced across the tarmac without hitting anything, The bump when it ran out of tarmac pitched the nose up, also jarred the mags to off.
My memory is that the 206 had enough speed to be just airborne when it hit a tree about 20yds further on. No wonder Dennis was upset.
