I've seen a serious proposal for a system which could bring down an
entire 747 by parachute in a serious inflight emergency (or individual
pieces if the plane should partially break up in flight). The problem is
again cost and mass; AFAIR it requires fourteen large parachutes fitted
to various parts of the plane.
