Hangars? Are Hangars at LHR still needed? The parking area those hangars stand on is needed- no hangars for maintenance in the future! I suspect those hangars might be standing on the future Terminal 6, but we really need that extra runway first. LHR will just be a cleaning/refuelling station for turnarounds!
Which is all fine and dandy until operational necessity requires an engine change/ Flap assembly replacement etc which prevents the A/C being ferried back out of LHR to CWL or wherever.
Might just about be workable without our lovely climate
