I've got another way of gaining access to a air-gaped network using a radish.
First you need to have access to the building and the opportunity to get close to one of the machines.
Place the radish on the desk to the right of the machine.
Then say to the user "Oh look a radish"
When they turn to look and pick up the radish you quickly slip a 4g dongle with an sd card loaded with malware and you're good to go.
I think this has more chance of success than the technique developed using a scanner, it's cheaper too as radishes are much cheaper than drones.
