Having an unwritten agreement about your boss looking for the black smoke column after the third day works too...helicopters make very nice signal fires. Granted there is not left to overhaul or sale if done right
Dont forget the logbooks. They burn very good and are usually necessary to be destroyed, to take care of making up all the flight time and ADs, Discrepanciese etc that were on the machine. Gonna burn the Boss' toys, make sure you burn the books........Ha Ha
