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.
