We boring old farts will have to beg to differ on reliability; but I remember the thump under your feet and the sparks from the jetpipe beside you as clear as today. And ssssSO OFTEN!
I was Bar Officer 848, A Flight, Bario under Dick Steil, also in QLD now. You and I only ever flew twice together according to my little blue books. Incidentally if the Bar Officer's Whirlwind 7 at Bario had coughed even once we would never have had any beer from Labuan and you wouldn't have someone to argue with now.
Difference was the Wessex could afford to cough (and did!) and the Whirlwind during my time there could not.
Nuff said.
