I basically posted this for the strong impression even a 5.5 seconds movie may make.
Then, I am a layman for aviation too. From news covering in Germany I may say that the whole story is under investigation now and we will have to await the findings.
Yes, I agree, it was kind of astonishing that the landing was tried at all. But, after recovering from this approach, he did it again at similiar winds (on the other runway). And many planes before him had landed at the same winds. So, the point is that landings at such strong crosswinds seem to be considered ok by professionals. I don't feel reassured, though. It was said the real problem was an additional sudden squall or gust of wind (and starting over isn't immediate because engines have to recover from idle to full throttle which the A320 is able to achieve within an impressive 2s -- still half the video
)
It was said the squall catched the plane
after the landing had already been abandoned, while engines switched to full throttle and that the squall pushed the plane down while it built up speed again.
