I was a stude, learning to fly helicopters on the Whirlwind (big aircraft, single jet engine which could, and was often, flown with a manual throttle!).
Trip 4, and I am wobbling back towards dispersal at Tern Hill. Both of us are wearing throat mics, combined with a bad aircraft intercom.
QHI says to me "Have you seen a Hover Engine Off yet?" I reply no. "You need to see one... crackle...... solo." He takes control, then says "Put your hand.. crackle... Speed Select ..crackle.." So I put my hand on the Speed Select Lever [like an automatic throttle]. He goes on "crackle... crackle ... retard it rapidly...crackle.." I look at QHI, QHI looks at me and nods his head. So I rapidly retard the SSL to Ground.
There is a scream from the QHI, the ac lurches around, controls move in a blur and we hit the ground like a jangling sack of spuds.
After a short period of silence, QHI says "F*** me, that one was for real. What I said ..crackle...crackle.. on the count of three, retard the Speed Select... crackle.."
Ah. But at least I got a tick for a Hover Engine Off demo!
