As of 14.35 (local) this afternoon, Heathrow has been closed to all inbound traffic due to an alleged gas leak. Aircraft are still using 27L for departures, but 27R has been shut.
Anybody got any further details?
Vidi, Vici, Veni. I saw, I conquered, I came.
27R has now re-opened and inbound traffic is landing again as of 15.20 (local).
Not yet, but according to other sources on the web, there were up to 55 aircraft in the hold at one point.
Anybody for RVSM? :)
