The aircraft doesn't care if it's blowing 300 knots, it just flies merrily along its' way.
But if that 300kts wind turns from a crosswind to a tailwind, within the space of a few seconds, you would expect some small alteration in the aircrafts flying position? Such as a loss of height?
In the initial video above, I see a Mallard travelling at a fairly steady altitude up until 17 seconds. At 18 seconds, it's losing altitude. At 19 seconds, the port wing is dropping dramatically. At 21 seconds, it's unrecoverable, due to a lack of altitude.
What is difficult to see in the video (due to the angle of videoing), is if the loss of altitude and port wing drop, is purely attributable to increased AOA, or loss of airspeed, due to initially flying too close to stall.
