This had a certain "how many angels can dance on the head of a pin" quality to it. Given that even the old guys at plenty of airports I've been to - during those rare occasions when mine has been flying - had never seen one before, that people have written to me, or posed questions on this forum, asking if anyone within three States of them had an airworthy one, that the notion of the Triple Tail Tour perished on the vine because nary a single soul would commit to even an off-forum email group conversation regarding any single event, not one of the four 14-19s at Kittie Hill (or maybe it was three) could fly (mine was undergoing an engine major), and the FAA can offer us no help here, the most precise answer we can come up with is:
DAMNED FEW
Of course I could relapse into that St. Crispin's Day speech from Henry the Vth about "We few, we proud few, we Band of Brothers," that I slapped into the TTT promo piece in the Newsletter, but I won't. Frankly the odds are heavily against us. They cost a lot to keep up, everyone has read what our own Lynn Ford had to go through to recover his, many languish for the want of wings, most forum readers do not have a flying example, and you can sell a Champ for more money than these fetch.
Point is that if you've got 'em, fly 'em because chances are you are among the last to ever have that privilege. And if you're working on one, carry on with a purpose but know you're doing it for love and that privilege. Love's labors lost among generations hence is more often the way of things than not.
