This was absolutely terrifying for a few moments. Basically your ears popped, there's a really loud bang and there was a lot of white noise. It was like somebody turned on a leaf blower in your ear.
This was absolutely terrifying for a few minutes.

I could feel that obviously my ears popping ... and then it got hard to breathe, and then, whoosh, all the compression in the plane was lost.
