When I was a baby flight instructor I, as with most instructors, rapidly learned a great deal about airplanes and the humans who fly them. Despite being a slow learner, some of those lessons stuck with me. Whenever I get into a discussion of the value of training for stalls, stall avoidance, spin avoidance and spin recovery, I immediately find myself in the right seat of a Cessna 150, a brand-new CFI with a student who has just intentionally stalled the airplane with full power and the flaps up. He has also unintentionally stalled the airplane with the ball about its own diameter outside the center of the race to the right.
