One of my best memories of over 45 years at LAP /Heathrow / LHR ,were the day an announcement was made that the "B ofB Memorial Flight"were giving a FLY By down 28 right so the off duty erks went to witness this event outside their crew room door ,Aviation's finest were using said runway for take off not a flicker of interest was shown of DC8s ,747s 757s and sundry other types even Concorde hurtling the runway ,plenty of aircraft in a long line on the holding point, in a short lull a Hurricane, Lancaster ,and a Spitfire flying in formation trundled along the runway not a dry eye to be seen . I don't suppose it will ever happen again it must have been the 40th anniversary of BofB MF or something.
