At what cost though? Like a single parachute without an automatic release system costs hundreds, if not thousands. You multiply that by 150 and it’s infeasible. Now include an automatic deployment system, and we’re talking tens of thousands per unit. Not including maintenance and repairs, long-term storage costs, the added weight on the plane.

Logistically, plane accidents that result in loss of life are so rare that it would make more sense to equip every car in production with ejector seats then it would to equip every plane seat with automated parachutes.
