When things go wrong on an aircraft there is sometimes little the pilot can do to keep it in the air. Ideally, then, aircraft should be fitted with parachutes for a safe descent in the event of an emergency. In practice, a big enough parachute would occupy almost the whole interior of the plane, so Daedalus has a plan to deploy a small parachute, but one that descends a little faster than the aircraft just before it hits the ground.
