Thanks, Cluin! I thought it was going to be from that movie where the airplane is loaded with the stoneworks of an old castle, being taken to the states and a gargoyle comes alive on the wing. Can't remember the name of it.

wingwalking;

HERE's their pdf info about what they can offer;

and, HERE is one man's experience, apparently with Utterly Butterly, as mentioned above.

Good luck and DO hang on!
