Back in the 1970s, while flying an MU-2 into El Paso, Texas, I heard the following exchange between approach and an airline crew after repeated attempts to get the crew to reduce speed:
"Flight 123, I must have you at 120 knots right now."
Captain of Flight 123:
"Son, do you have any idea of the stalling speed of this thing?"
"No sir, but I bet if you ask your co-pilot he can tell you."
