One of the babes in the office where I used to work, saw the picy of my Pitts on my desk and told me how much she'd like to "loop the loop".
A few days later I find myself house-sitting a nice S2A with an open front seat. I remember office babe and invite her down to come out to play.
Introduce her to the aeroplane, brief on the sortie, strap her in (one of the few pleasures in tandem aircraft) and taxi out, pre-flight check including a final check of her harness and off we go. Up to FL nosebleed and a last check to make sure that she is ready:
We do a gentle barell roll, "More, more!", through the headset.
Loop - she still wants more. I start running through quite a nice positive G sequence that I use to warm up
Loop into P loop into roll off the top into split S into stall turn into a super-slow roll into 1/2 reverse Cuban into up 45 into a 2 turn spin.
She's still happy but I feel it is time to head back. We are chatting away and I tell her that we'll be landing very shortly and identify the strip for her. At this moment I can see/feel (against my toes) her arse squirming around.
We land taxi back to the hangar and I shut down. I tell her to remain where she is (tube and fabric aeroplanes are very vulnerable to slightly dizzy pax). As I stand on the lower wing and lean in to help her unstrap I realise that BOTH seatbelts, crotchbelt and shoulder harnesses have been unbuckled and then re-buckled wherever was most opportune.
"Err, the seatbelts, have you been fiddling with them?"
" Yes, of course," she replied somewhat indignantly, "everyone knows that after take-off you can undo them and then you must do them up again for landing. I have been in a plane

before!"
"You've been in an AEROPLANE before?"
"Yes, me and Denise from the typing pool went to Ibiza with Monarch and that is what the Captain told us!"
Just as well we didn't try anything negative
Needless to say I know let my front seat pax know of this tale SO that it couldn't happen again
