Boeing’s 747-400 aircraft, first introduced in 1988, is still receiving critical software updates through 3.5-inch floppy disks. https://www.theregister.com/2020/08/10/boeing_747_floppy_drive_updates_walkthrough/ 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.
While it might sound surprising that 3.5-inch floppy disks are still in use on airplanes today, many of Boeing’s 737s have also been using floppy disks to load avionics software for years. The databases housed on these floppy discs are increasingly getting bigger, according to a 2015 https://www.aviationtoday.com/2014/08/29/teledyne-brings-aircraft-information-management-into-21st-century/ report from Aviation Today. Some airlines have been moving away from the use of floppy discs, but others are stuck with engineers visiting each month to sit and load eight floppies with updates to airports, flight paths, runways, and more.
The 10-minute video tour of the 747 (above) is a fascinating insight into the parts of the plane you never get to see, particularly on a decades-old airliner. The tour is part of this year’s virtual Def Con conference, the US’ largest hacker conference. As modern planes rely upon ever more sophisticated technology, security researchers are increasingly interested in how planes prevent passengers from interfering with flights.

Security is particularly relevant when it comes to in-flight entertainment systems. A cybersecurity professor https://go.redirectingat.com?id=66960X1514734&xs=1&url=https%3A%2F%2Fwww.linkedin.com%2Fpulse%2Fbuffer-overflow-exploitation-british-airways-system-marco-gisbert%2F&referrer=theverge.com&sref=https%3A%2F%2Fwww.theverge.com%2F2020%2F8%2F11%2F21363122%2Fboeing-747s-floppy-disc-updates-critical-software discovered a buffer overflow exploit onboard a British Airways flight last year. The professor was able to use a USB mouse to input long strings of text into an in-flight chat app, crashing the entire in-flight entertainment system for his seat. Security researchers are still hunting for vulnerabilities that would allow them to communicate with flight systems from publicly accessible parts of planes.
A focus on security is even more important on the latest aircraft. Modern planes like Boeing’s 777X and 787 use fiber networks, where all the avionics plug into this network and are controlled by a pair of computers that run flight critical software. It’s more of a traditional network like you’d find inside an office building, and some of the latest airliners even receive software updates over the air. The software that powers modern aircraft isn’t always reliable, though. Boeing only just https://www.theverge.com/2020/5/27/21272478/boeing-737-max-resumes-production resumed production of its troubled 737 Max airplane after software glitches led to https://www.theverge.com/2019/3/22/18275736/boeing-737-max-plane-crashes-grounded-problems-info-details-explained-reasons two fatal crashes that killed a total of 346 passengers and crew members.
Despite modern technology being available, it hasn’t stopped floppy disks from persisting in other industries. The US Defense Department only https://www.theverge.com/2019/10/25/20931800/usa-nuclear-8-inch-floppy-disk-solid-state-transition ended the use of 8-inch floppy disks for coordinating the country’s nuclear forces in October, and the International Space Station is https://www.theverge.com/2018/11/22/18107919/international-space-station-floppy-disks-discovery-iss full of floppy disks.
