Anybody have a clue as to why it would take those experienced Lufty A321 pilots (after pressing those easy-to-reach overhead "QEB-48" buttons) 4000 feet of altitude loss to recover?
My guess is it took 4000 feet to assess situation combined with the startle factor to implement right procedure. Thankfully the crew responded accordingly and had the altitude. Lesser crews and other factors thrown in may have resulted in a different outcome.
