With our 9x9 film camera we can fly 600 pictures at high altitude or many thousands at low altitude before we have to land for fuel. Each frame of film is 1.1 gig when scanned. The digital camera has a 2 TB solid state RAID. That will outlast the fuel as well unless it is low altitude.
The logistics is totally different. During a big mapping project we can just keep adding another roll of film no problem. With digital after a day of shooting it takes a while to copy all the data off and you have to do that twice for redundancy. Then erase the data cartridge before the next flight or get a different very expensive data cartridge.
Try to copy one TB of data with error checking from one drive system to another. It just takes a while. You have to do it twice to have a redundant copy in case of a bad hard drive or copy error.
