No, it is NOT for explosive or sudden decompression. The masks deploy at a cabin altitude of 14,000 feet. Period. Please explain how to override the automatic deployment of the passengers oxygen system.
Okay there wasn’t an override. The Iranians or the pilots caused a sudden decompression and everyone died of hypoxia shortly thereafter. That isn’t very difficult to do.
Are you happy now???
Ground crew disables them? tampers with them, cuts the air hose, makes them unable to drop by applying super glue to the overhead panels?
Inject each one with a few cc’s of sarin?
