Nomore, when was the 'last time' ?
A lot has been built on the site since the closure, and what remained for several months of the runway & taxiways has been utterly demolished ... at least that's what it looks like from the M7.
Back of the envelope calcs: a spare $250M might get you ownership, very rough figures you understand, that would mean the owners of each of those proposed 20 houses stumping up $12M or so. That's without a dime spent on rebuilding the infrastructure that has been dug up, nor demolishing what is there now.
Sad, but reality.
