I found an account of the accident that mentions the 33 Egyptian army officers:
Flight 990 was 100% proven to be an intentional act. Just because the Egypt govt. doesn’t accept the findings doesn’t make it any less so. The govt. of Egypt acted like a man convicted of murder who was dragged from the courtroom screaming “I’m innocent!”.
Not only did every piece of evidence(cockpit recordings, black box, etc) point to First Officer Gameel Al-Batouti crashing the plane intentionally, but there not a SINGLE piece of evidence that pointed towards ANY other possible cause. Not one.
Instead of doing the morally right thing and accepting the NTSB findings, the Egyptian govt simply said “no way!” and refused to accept this. They went into a state of chronic denial.
The US, in trying to be “PC” and keep some diplomacy, caved a bit and modified the findings wordings so as to leave a little wiggle room.
A very shameful thing.
To this day, it remains one of the worst mass murders in US history.
