Also, we have another....intersection takeoff are not allowed, except in the case of part of the runway being closed.
Perhaps BA should adopt a similar policy?
I would suggest that is fine in an ideal world, but it is not a really practical proposition. The important thing is to have in place the procedures and checks to try to ensure that the holes in the cheese don't line up. Clearly in this case all the holes bar one (the aircraft was light) lined up. That is clearly regretable and the procedures will have been modified as a result.
You can bet your shirt that those pilots will never make that mistake again!
To suggest that you should use full length of 31L at JFK, as an example, rather than KK intersection, is frankly ludicrous, but undoubtedly that is what 411A would do.
