A few years ago I had a Mate who requested that his ashes be spread over the Waikerie Airfield...in a special way!
Taxied the Gliding Club's Pawnee out into the centre of the airfield, parked it and locked on the brakes.
Large sheet of plywood placed under the tail wheel and ashed poured onto the plywood just aft of the tailwheel.
Started Engine and went to about 1800rpm with stick firmly back!
Took surprisingly quite a long time to blow all the ashes away. About 5 minutes IIRC.
: RIP Schultzy.
