Captain 'Hoot' Gibson of TWA 727 fame, is the man to ask about flaps at high altitude.
- to introduce this 'history' into this thread demonstrates a complete lack of understanding of aircraft performance and the topic.
Why not tell us EXACTLY what happened and then everyone will see the irrelevance of the posts. Did he
climb above 20k with flaps extended? Did he
extend flaps above 20k contrary to the limitation?
