Just a couple of things;
Suddenly, a strange aroma, like an electrical transformer, floods the cockpit, and the temperature suddenly increases. At first, the younger pilot thinks that something is wrong with the air-conditioning system, but Robert assures him that the effect is from the severe weather in the vicinity. Bonin seems ill at ease. Then the sound of slipstream suddenly becomes louder. This, presumably, is due to the accumulation of ice crystals on the exterior of the fuselage. Bonin announces that he is going to reduce the speed of the aircraft, and asks Robert if he should turn on a feature that will prevent the jet engines from flaming out in the event of severe icing.
That smell was from St Elmos fire and that noise was from flying in very heavy rain. Those two usually go hand in hand. That "feature" was probably auto ignition.
A stall is a potentially dangerous situation that can result from flying too slowly. At a critical speed, a wing suddenly becomes much less effective at generating lift, and a plane can plunge precipitously. All pilots are trained to push the controls forward when they're at risk of a stall so the plane will dive and gain speed.
This is typical rhetoric from someone without a very good understanding of basic aerodynamics. A airplane can stall at any attitude and airspeed (within structural limits of course) by not so much as flying slowly
but exceeding the critical angle of attack Think about your accelerated stalls. The rule you learn in a basic acro course is to point the nose in the direction the aircraft is going to get it to fly again. Case in point:
By now the plane has returned to its initial altitude but is falling fast. With its nose pitched 15 degrees up, and a forward speed of 100 knots, it is descending at a rate of 10,000 feet per minute, at an angle of 41.5 degrees.
The nose would have had to be pointed in this case down to very close to 41 degrees since it does not have the power to fly out of that condition. Then letting the aircraft accelerate then retarding the power while pulling out of the dive. Pointing the nose down that much would seem very alien to most people however that is what was needed to survive at that point. The 1st problem was putting the aircraft assume that stalled condition, the second was not recognizing it and implementing correct recovery procedures.
