So many questions about stalls
More:
1. Why did the pitots ice up?
2. Why did the A/P and A/T disconnect?
3. Why the zoom climb without clearance from ATC?
4. Why the sudden reduction of speed at top of climb?
5. Why when at the same time the plane went into the thunderstorm?
Any connection?
The unanimous comment from my group of old retired pro's: Why didn't they deviate?
Comment: When an airplane comes out at the top of an uncommanded zoom climb almost 3000 feet above their max altitude below 60 kts, it is out of control! The flight controls do not have ANY effect. As we have seen until it hit the bottom.
Thunderstorms are known to contain strong up and down drafts. For 50 years we in the pilot community have been warned to avoid, avoid, avoid them.
