As an aside, I was once repsonsible for a fleet of airline catering trucks. To give a perspective from the other side as it were, we would routinely be crapping ourselves within 10ft of any aircraft - our SOP was pull up 20ft away, drivers mate jumps out & stands 2ft in front of fuselage doorway & guides truck into position at a crawl.
It would really have been the end for any member of staff who smashed up an aircraft, so we took it very seriously as everyone within the ramp boundaries should.
Didn't stop us from smashing lumps out of a compressor on the LGW south term road & knocking out the aircon in the middle of August though.
