when you are working late at night welding together a new QEC (Quick Engine Change) Stand for an F4u-4 Corsair when an F-15C taxis by on the taxiway by my hangar and about 5 mins late you feel your insides vibrate and your eardrums reverberate with sheer trauma as he lights up his afterburners and blasts into the night above Colorado Springs leaving a 50' trail of blue flame!
That is pretty damn impressive... anyways, back to work for me...
