A logical extension of this kind of "policy" is surely that when there are heavy crosswinds making landings difficult we might wind up with "level crossing gates" on motorways that will be closed as every arriving aircraft comes in - just in case something goes pear shaped.
At some stage this country has got to get a grip, accept that we don't live in a risk free environment, and that restore some rationality to assessing risk, and managing said risk.
It remains to be seen whether the Jet2 incident last weekend was serious, hopefully if it was it will be properly reported through the usual channels.
Motorways lane / complete closures are another example highlighted above. Drive on the continent as see how few km of cones there are ahead on roadworks or lane closure ahead of an incident. 1000m is normal for road works, often less for incidents, and curiously people cope by driving accordingly - as they would in UK.
