When a student on No 16 Vampire/Varsity course at Oakington in the 60's I was told about the "civvy" who, in WW2 and before first light, cycled to work round the perimeter track.
They were equipped with Stirling bombers with their extended undercarriage legs that ensured the four engines had plenty of clearance under them. Knowing this he would remain on the taxyway rather than take to the grass to pass them.
Sadly they re-equipped almost overnight with Halifaxes and he still took his usual short cut..... but through the props rather than under them.
