Just got out my copy of "Handling the Big Jets" by D.P. Davies (3rd edition, reprinted 1997 c. CAA), he included a sub-chapter on aquaplaning and finised with the following summary:
"This sub-chapter on aquaplaning has been written rather forcibly - and for good reason. While some accidents are truly unavoidable and others the result of a most unusual chain of circumstances, aquaplaning accidents are nearly all avoidable. It is not the end of the world to stand off or divert occasionally. But it is asking for trouble to attempt a landing on a tight, very wet runway. Think well before you expose yourself to this kind of risk."
This is no way is intended to pre-judge any accident investigation, but just a reminder to one and all that risks are involved in aviation.
