That is Alain Decadenet...not sure of the spelling on that one !...and the Master himself, Ray Hanna (gone but not forgotten !). The breifing was for a low flyby, Ray took off, lifted the undecart and essentially stayed at the same height for the duration of that run. We've discussed it many a time on other forums and reckon on around 4.5 to 5 feet clearance from the prop to ground during the run just prior to pull up.
Oh, almost forgot, the Spittie is MH434, Rays fave mount. !
Is a classic !
