What always bugs me, is the fact that virtually no-airport is using EMAS at all ! Some do of course, but this should be kind of a requirement, instead of the loss of lives and a write off; if would be an inspection and a replacement of the affected blocks ( especially at airports where the perimeter ends with a ditch/cliff/motorway/warehouse,etc.)
If the industry is learning from this one ( it did not from the Challenger in TEB, or AA, AF, ); EMAS would come as more standard than anything else on a runway construction plan, no ?
