There were some interesting/important issues raised in the BBC programme - I was enjoying the discussion here and didn't see the need for the flippant crap - there's another (similar) thread in JB for that
So no problem with the sense of humour - just an issue with the "humour"
As for "facts":
Fact: Winter 1995/1996, Surrey Police close one side of M25 whilst Kent police keep other (opposite direction) side open (or vice-versa) - promise that new co-operative procedures will prevent recurrence.
(Scene in BBC prog where Surrey/Kent diversions "meet")
Fact: January 2003, several motorways gridlocked/blocked due weather/accidents - many dozens of people stranded, some hypothermic - Govt. launches inquiry to understand issues and prevent recurrence.
(Several scenes in BBC prog where this was illustrated)
Fact: After the Clapham and Southall train crashes the new systems in place (or about to be in place, or being investigated) would prevent recurrence.
(Waverley - the catalyst of the BBC prog)
Fact: 1997, go-around at Heathrow nearly catastrophic, procedures changed to prevent recurrence.
So are we saying the whole programme was wrong?
Are we saying only the bits that related to ATC were wrong?
Are we saying that it might be close, but not under those exact circumstances, so let's dismiss it?
Are we not 100% sure?
Or what
