An emergency drop system allows ballasted advertising banner ( 14 ) if disconnected from an aircraft to descend slowly to the ground. Banner ( 14 ) is suspended below an aircraft by line ( 4 ) held taut by ballasted container ( 24 ). Static line ( 26 ) attached to the aircraft will, on release of loop ( 6 ) of line ( 4 ) from the aircraft, pull on closures ( 12 ) and release parachute ( 8 ) from its container ( 10 ). Drag of parachute ( 8 ) in the slipstream will slow the fall of banner ( 14 ) and also pull on lanyard ( 20 ) so that it activates 3-ring release ( 22 ) causing container ( 24 ) to invert and disperse the ballast.
