I have aquaplaned in a 737 NG and it is not pleasant. The crew were put in a difficult position with the workload pretty high.
I found the report frustrating in that it didn’t bother to mention the Runway length until quite late in the picture. Once I eventually found it was only 1700m, I was very surprised that they chose Autobrake 3 rather than Max as the NG is not a good stopper.
I also couldn't see see whether they had Carbon or Steel brakes?
