Might be a cross-cultural issue here. "Good one, Skippy" is a genuine mateship accolade in Australia. Remember the kangaroo in "Crocodile Dundee" that shot back at the hunters? Maybe in some other parts it means something else...
19,200 feet is well above Everest (or XV, or 'b') base camp. Where were you? I would think that the thinner air could be helpful for speed, and of course the slightly lower gravity value could make for higher PV records. Shame they never tried it at Tranquillity Base.
