Going back a couple of pages
Didn't the 727 Greenline start at Luton then went to Watford, Maple Cross, Heathrow and finally Gatwick?
I used to catch it at Park Square if both ny car and bike were off the road together. Took about 1 hr 15 to West Drayton then a 10 minute walk to LATCC. OK when going on an afternoon but didn't work for other shifts.
There was an RF4 hangared in the club hangar in the mid 60s; sorry can't remember more about it
