passenger jet ejection system

Earlier in the year a passenger plane landed on the hudson river… then an air france plane crashed in the atlantic. Passenger planes should be able to detect when they’re nearing water and automatically ‘eject’ either the passengers or part of the airplane to improve chances of survival. Planes will typically break up when they hit water and if they don’t, chances of survival are low – a bit like being trapped in a sinking car. The roof of the plan should come off or some sort of cushion / airbag-like feature should activate underneath the plane to lesson the impact of hitting water.
