Touchdown! Greaser!
I've done this once.
I used this approach: Attach the bag of ashes to a string, with the other end attached to something fixed in the plane (like the seat rail). "Gently" perforate the bag in a couple places with a knife, so that when you throw the bag out the window, it starts out intact, but when it gets to the end of the string (far from the cockpit!), the bag fails, and the ashes are released.
When I landed again, all I found outside the plane was a string with a little bit of tattered bag at the end of it. No ash on the plane inside or outside.
There are pics in this thread. You posted at least one of them.
I was referring to kath's post jokingly....
