I was a bit annoyed that my one spare day in Tokyo was a rainy one. I didn’t have any great plans for the day other than getting adjusted to the time but, when I knew it was raining, I almost didn’t even bother with Haneda. However, in the absence of another plan, I decided to go. The thing I liked about it was that, with the rain falling, the runway was wet. This resulted in a lot of moisture being thrown up in the air by the jets as they reversed thrust. Some went for minimum reverse but others went for a bunch of throttle as they aimed to stop in time for the exit they were aiming for.
