Well, according to http://www.hochwarth.com/misc/AviationCalculator.html I was pulling about 0.19491 MACH on my way to breakfast on Saturday in my RV-12. Clearly those thousands of raised pulled rivets reduced my speed by at least 0.00805 MACH. Takes a big man to admit that his pitot tube might be a little short....will be sure to keep the cover on it when I'm on the ground now on, as I wouldn't want to embarrass myself in front of those other RVs with longer tubes...

The stall vane and pitot tube are sharks waiting to bite. Early on I left my pound of flesh on both, but I figured it out pretty fast -- a beat dog is a wiser dog! I wouldn't experiment with cutting it shorter as it would be a real PITA to replace a pitot tube!

It did seem to take you a long time to get to smoketown. Regarding the governor's tube, he has boasted about his being the longest in the fleet, but he is not boasting now that it has sheared off
