At a meeting once, the infamous TJ answered that we would get the offending aircraft bulldozed off the runway.

Good luck finding a willing contractor in a timely manner at YPPH. True story, on a recent public holiday a simple fuel spill on one of the stand off bays closed a bunch of them all day and late into the night. No contractor willing to be called out at any price. Chaos ensued.... Caveat emptor
