I was in the ATC 147 squadron 75 to 79
I can still remember a flight in a Chipmunk from Exeter where I took control for the first time after I handed back I was told
"You did OK but keep the nose down"
With that we were diving at an angle that seemed near vertical and it felt like the world was going to fall out of my bottom.
and the icing on the cake was the sign right in front of my nose
DO NOT DIVE THIS AIRCRAFT AT SPEEDS
IN EXCESS OF 165 KNOTS
My eyes were glued to the ASI
We pulled out at 163
