Flying a Remote Control Airplane (usually a glider) so high you loose sight of it and never see it again. Or the exact opposite of a lawn dart "Diggs" is well known around the large remote control airplane community. Even more well know is the fact he has lost 4 of the SAME REMOTE CONTROL PLANES by flying so high he looses sight of them and they are never seen again.
One of the pilots in the competition pulled a Diggs. Its time to bring that plane down before you pull a Diggs and free the plane.
