In Mid '70's my most direct route from home to work involved the perimiter road, though BEA and BOAC Engineering and along the north side and out by the pub at Colnbrook (name).
One day, probably '72?? just after the Munich games massacre racing a prop job as it took off on 28R, in my Hillman Imp. was brought to a screaming halt by the army road blocks, tanks and guns and spent the next 3 hours trying to explain I was not a terorrist!!
, Brother who worked at Heathrow had to come and verify who I was
Heathrow was not the same since.
Happy Days
