deceleration produced by barriers like that
would have killed everyone on board this aircraft had they been in place.

That's barriers, not barricades. Foam barriers are being installed at most
large airports at the ends of the runways. They are made from special cement
which crunches when landing gears run through it thus decelerating the
aircraft with minimum damage. It is an excellent idea for airports such as
TEB.
