If I recall, in the UK it started when a catering(?) truck hit a 747 at Heathrow about 15 years ago.
All of a sudden my camera crew vehicle insurance had an exclusion clause…
A right pain as we then had to cart our crane and lighting kit through hangers.
Insurers then stung production companies for airside cover which then allowed our vehicle aside, I used to have two cigarette lighter powered magnetic amber hazard beacons to look the part
However these days it is more difficult to get a private vehicle airside at large airports.
When rigging helicopters at large airports there is usually a line outside the hangar door that for the purposes of needing a security pass at least, is deemed "airside".
Step over the line without high vis and a pass and you are in strife.
In oz the door from reception into the hangar is meant to be controlled with contractors and visitors needing a company pass.
All good stuff to stop the uninitiated wandering outside the hangar and god forbid a nutter in a van.
I was on a shoot when a production assistant doing an early morning coffee run drove her red mini across the runway at Biggin Hill just as it became active.
