An airframe every year or two falling out of the sky from cruise killing hundreds.
Sims not accurately programmed to train for scenarios that can and do happen in extremis.
Is it time to fit an ejector seat in an old 319/320 airframe and possibly also 330 and send a test pilot up to find out what REALLY happens. What the plane really handles like. What the recovery techniques all current pilots on type would lead to if done expeditiously. And not.
I'd prefer a man with an ejector seat to find out on his own that "putting 90 degrees of bank angle on to drop a wing and get the nose down" can be done, retains control authority an structural integrity. Rather than when I'm sat in seat 9A reading my book and planning a nice weekend.
Just saying...
