I can think of several reasons - don't know what is the primary one, though.
- An aircraft and a fuel bowser can each accumulate a lot more static electricity than a car (and at a car filling station the gas pump is already grounded).
- Aircraft and fuel bowsers are a lot more expensive than a car, so some extra precautions are useful....
- The flow rates during aircraft refuelling are such that they can themselves generate static electricity.
