2 h 12 min 07 at 29,736 feet altitude, the PNF said, “No above all don’t extend (the)”
As I read this, the adrenalin flowing from each of the guys sitting in the cockpit was enough to override their ability to evaluate their surroundings.
3 seconds of speed brake is enough to feel deceleration if you have speed. They felt next to nothing at the AOA and speed that they were actually at. They would have had to sense a non-event in order to realize its significance, i.e. NO deceleration-Why?
