Abstract
An airplane parachute device includes parachutes and release mechanism mounted in the upper surface of the aircraft's fuselage. A releasable hatch, covers each parachute and release mechanism, and is in operable communication with the pilot's compartment to allow for remote controlled release. The parachutes are under similar remote control and are ejected from the parachute compartments by a coiled spring system. Each parachute is aided in opening by an inflatable collar affixed to the outer rim. A shock absorbing piston is mounted to the bottom of the parachute compartment and to the tether lines of the parachute.
