You can get cameras up to 50MP res over the counter.... You can get expensive Hasselblad that do something fancy with the sensors and produce a 200MP image but as the aircraft is moving this won't be an option.
I have a film scanner on my desk which can spit out 90 MP res and 24 bit colour on a 35mm film. Consumer Medium format scanners are 180 MP res and 24 bit colour.
As much as people love the ease of digital photography large format film digital can't touch even remotely for resolution or quality.
