THAT was a ride I won't forget.
In 1979 I was jumpmaster on a C130 at Fort Bragg. About 15 minutes out from Sicily Drop Zone, we got an electrical fire up front where the radios and amplifiers are located under the flight deck. The only jump commands were stand up, hook up, and go. I bet we unloaded 64 paratroopers in less than 15 seconds. Plane landed safely back at Pope AFB, but we spent about 12 hours tracking down jumpers from Southern Pines northward. That will pucker up your asshole.
Fortunately the pilot took that alarm seriously or you could have ended up like Helios 522: https://en.wikipedia.org/wiki/Helios_Airways_Flight_522
Rapid Decompression. Did the masks drop? This happened to a friend of mine and she started having all kinds of sinus problems afterwards. About 2 or 3 years with dealing with all kinds of issues, they finally did a CAT scan and learned that the decompression incident caused the lining of her sinus to tear loose.
