1) You.... realize that this is a comic book movie, not a documentary about 1984, right?Apparently based off of the Panavia Tornado from what I could find, but moved it to a side by side instead of tandem seating. Also, a weird choice because what is a plane doing at the Smithsonian fully fueled ready to go that has only been in service 4 years at that point? (the tornado came into service in 1980 and saw its high point during the first Gulf War).
Then again, in the video game scene there were video games not invented yet in 1984, and Steve (WWI pilot) wouldn't have any idea how to fly a modern jet, and it would be impossible to fly to Cairo, and MK19 grenade launchers apparently fire the entire cartridge in 1984,...and...and... You'd think with that budget, they could afford to at least talk to a military consultant first.
2) In 1984 the tech being used on the comics book pages could at best be described as "inspired by...."
3) It is an established fact that the DC film Universe is in fact a Multiverse. So maaaaybe, just maybe, the mundane stuff in the 1984 we're seeing on screen developed slightly differently/earlier than it did here on our own world.
