Windows 3.1 saves the day during CrowdStrike outage — Southwest Airlines scrapes by with archaic OS (www.tomshardware.com)

Southwest Airlines, the fourth largest airline in the US, is seemingly unaffected by the problematic CrowdStrike update that caused millions of computers to BSoD (Blue Screen of Death) because it used Windows 3.1. The CrowdStrike issue disrupted operations globally after a faulty update caused newer computers to freeze and stop working, with many prominent institutions, including airports and almost all US airlines, including United, Delta, and American Airlines, needing to stop flights.

Windows 3.1, launched in 1992, is likely not getting any updates. So, when CrowdStrike pushed the faulty update to all its customers, Southwest wasn’t affected (because it didn’t receive an update to begin with).

The airlines affected by the CrowdStrike update had to ground their fleets because many of their background systems refused to operate. These systems could include pilot and fleet scheduling, maintenance records, ticketing, etc. Thankfully, the lousy update did not affect aircraft systems, ensuring that everything airborne remained safe and were always in control of their pilots.

Windows 3.1 did have a BSOD. It wasn't always fatal, you could try to hit enter to go back to Windows, but most of the time it wasn't really recoverable, Windows often wouldn't work right afterwards.

I ran into them all the time in 3.11 on our 486 which had some faulty RAM (the BSOD would even be scrambled). If we could get back to Windows after that, it'd just be in a zombie state where moving the mouse around would paint stuff over whatever was left on screen, and wouldn't respond to clicks or keypresses.

Fun times.

IIRC Windows 95 did that as well
