The best thing is a tube like a postal tube hang that out the window it
will suck the ashes into the tube and out of the aircraft


That really depends on the aircraft you're using. The ashes are abrasive, so
if the ash plume will hit the empennage or wing, then the tube idea is not
such a good option - - unless you plan on doing some refinish work soon.
