What a load of crap! You forgot to mention the accident rate of Tigers in the 50's !!!!!!!!
Depends where you were flying of course. I had over 1000 hours as instructor on Tiger Moths in the RAAF over the period 1952-4 as well as a few hours crop dusting at 6000 ft density altitude and and the only prang I saw was when the CFI taxied into an unlit Christmas tree at night. Can you quote the accident rate statistics on the DH 82 when compared with comparable types especially as the Tiger was the primary trainer in Australian aero clubs in that period. Tee Emm is right. You don't need an aerobatics endorsement in order to qualify to fly a tail-wheel type.
