Frank told me he witnessed Jack not long after the Korean War perform an inverted run along the main street (of what he believed was Warracknabeal) at 200' circa early to mid 50's.
Nice photo of a Mustang. I very much doubt if Jack McD. would have risked such a foolish and highly dangerous manoeuvre. A lot of these "daring pilot" stories of various pilots are embellished down through the years and the truth is very different. Jack was the consummate air-show pilot in the Mustang and in the displays that I witnessed back in that era he was ever careful of the rules of low level aerobatic displays in the Mustang.
