Me, I was a passenger once in one of those machines back in the days when the SAAF still use to operate them out of Lanseria. On the climb-out to Hoedspruit and passing about 7500' the engine started to splutter and run realy rough. The Captain merely took out his clipboard and started recording the engine parameters. When asked what was going on, he replied "they do it sometimes"!. Realized then that you require b@lls as big as avo's to fly those things!!!!!
Me, I never flew in one again. Went on to fly bang seats. At least there you have one more option!
