Surely a wise man learns not from his own mistakes but the mistakes of others? Thus preventing him from making the same mistake him/herself?
I've made some non costly mistakes, we all day everyday whatever we are doing. I was flying an Arrow yesterday on my own and thought I would try a couple of stalls on the way as I wasn't in a rush. HASELL checks completed I tried a clean power off stall first. There goes the warning horn, bit fast I thought at 80 kts but yoke forward, ball in middle, horn still blaring. Arrow by now making like an arrow, bit more power, horn goes off, recover having lost about 500'. Most unusual I thought. Tried a gear/flaps down with power stall. ASI down to around 50 kts, yoke hard back, there goes the horn, wings get confused, yoke forward slightly and instant recovery....then the penny dropped and I flew on feeling like a clot...
