All it needs is one really bad accident at LHR - eg someone ploughing a 380 into W London suburbia - and I think you'd be amazed at how fast LHR might be closed down
Great point as ever mate. Best not have any overflights over London just in case Lufthansa or KLM inadvertantly drop a B747 into Hammersmith or a passing transatlantic Emirates A380 drops into an Arsenal home game. Best also close LCY with a flight path over Parliament, Trafalgar Sq, Tower Bridge, Downing Street and MI6 when they're on 09 !
btw what makes ploughing an A380 on final approach any more likely in London than anywhere else. Life is risky, deal with it, BA038 should be seen as a one off event, as one hopes OZ214 where a qualified crew banjoed a commercial airliner in CAVOK broad daylight. Risks are managed and mitigated but never go away, perspective tells me that crossing the road in London is still riskier.
