Rifleman Ozzy - - I am working on a new one for you.
Passing under the Coronado Bridge in Diego. Immediately looping and passing under it a second time at the bottom fo the loop.
Have accomplished it numerous times in vintage craft.
Have tried it twice at speed and failed so far. Clipping the bridge deck on second pass each time. So close, though!
I am using a Voodoo in full power dive so first pass under is at about 1200 knots.
