You know how the military works... you hand down techniques and "techcedures" from guy to guy and everyone knows them. Then some dudes get in a rush, forget to turn the pitot heat off after a ADC calibration and after destroying a pitot static system get crucified. If they had turned the pitot heat on and it doesn't say to do it in the TO, some AIB weenie would crush them for not following procedures when they damage the jet. Don't turn it on and you crash the jet. I think we should be more concerned that a B-2 can be brought down by a squirt gun .
