If you look at the M4, M3 and M40 "corridors" you will find many non-UK
businesses. There are all sorts of reasons why they set up there but
the proximity of Heathrow has often been cited by such companies as one
(not the) reason for locating there.

Companies selling (mainly American) computer parts and other electronic
components set up in the 70's along Bath Rd Slough precisely because of
the proximity to Heathrow. Not only did it allow transatlantic visitors
easy access, they could pop to the airport to pick up their inbound air
freight most easily. This spread along the Thames Valley to Reading, and
eventually Newbury (and beyond).
