Boeing’s 747-400 aircraft, first introduced in 1988, is still receiving critical software updates through 3.5-inch floppy disks. The Register reports that security researchers at Pen Test Partners recently got access to a British Airways 747, after the airline decided to retire its fleet following a plummet in travel during the coronavirus pandemic. The team was able to inspect the full avionics bay beneath the passenger deck, with its data center-like racks of modular black boxes that perform different functions for the plane.

Pen Test Partners discovered a 3.5-inch floppy disk drive in the cockpit, which is used to load important navigation databases. It’s a database that has to be updated every 28 days, and an engineer visits each month with the latest updates.
