“And hydroplaning not being a function of airplane type”
But hydroplaning is related to the type of tyre and tread depth (which may be related to the aircraft maintenance manual).
The hydroplaning speeds of many modern tyres do not corespondent with general rules of thumb (9/P), often with a wider spread of speeds.
Was the 737 thrust reverser mechanism changed to give greater airborne integrity after the Lauda accident ?
Was there any effect on the ease and reliability of ground selection; does this differ from other types ?
Does the 737 landing performance over-rely on thrust reverse ?
