Thanks! Of course the tailfin in my post shouold have been written as 'swaying from side to side, rather than backwards and forwards (which would mean you were about to be deceased!). A darn good diverging 'Dutch Roll' rolling each side is absolutely frightening. And doing stalls to stick push on the VC10 in an air test was awful to me. The most frightening flying I ever did, with the memories of the BAC1-11 and 2 Trident accidents (T-tail superstalls) so fresh. The AofA indicator would get to 15 degrees and hover, then the push would go, horns blaring, 95 kts indicated, and you would pitch violently down- which meant you would live! That was the end of any ambitions I may have ever had (which I didn't) to be in any way a 'Test Pilot'! I had been lying in bed on a sunny Sunday morning when they called me out to do that on standby! I hollered about it so loudly afterwards that i think they restricted test flights to volunteers only after that. Not me Baby!
