Which is why aerodynamic forces cannot change very fast. The lift has the maximum upward value at stall - AoA about 15...20 degrees - and maximum downward value at inverted stall - AoA about minus...

Erratic flying

So, it is proven that both engines remained on the wing and running until impact.

What parts of the airplane DID get lost before impact and form those three separated debris fields?

Letīs compare this against a "null hypothesis" - that the 3 isolated debris fields were contributed to 3 pieces of aircraft that separated from the aircraft at one event, then ended up in different...

Then letīs answer with basic physics.

If you drop from an aircraft two items of equal size, one heavy and another light, which of them will stray further from its predictable route?

The lighter...

While flying with transponder left turned off is illegal, it is probably not that big deal, compared to the safety of airframe in respect to things like overspeeding, upsets and structural integrity...

Does it mean that e. g. the transponder only knows the altitude (it has no way of knowing what the underlying terrain is or what the local barometric pressure is)?

So, the transponder does not...

Or above Vd.

The 757 that rammed Pentagon is said to have flown at 530 mph. Definitely above Vmo (it is said to be 350 Kias, so about 390 or so mph). What is the Vd of a 350?

It then seems that...

This is connected with the concept of Vmo.

Basically, the faster an aircraft flies, the larger the drag (at the same height). But the higher the aircraft flies, the lower the air density and...
