Very little mention (one paragraph that I saw) in the report deals with grooved vs. ungrooved runways. I do not understand why every airline runway is not grooved, particularly in this part of the world where high rainfall rates are common.
Would a grooved runway have prevented the overrun at their high energy state? No way (that I am aware of) to calculate. A grooved runway in Toronto would have probably prevented the Air France A-340 in Toronto.
The holes in the swiss cheese really lined up for this accident to occur. But knowledge of the runway not being grooved, particularly with a tailwind, should have further emphasized the importance of touching down "in the zone".
