This may seem minor, and is easily fixable if using the editor to make missions, but the F-4 pilots default to wearing a parachute. If they eject, they are still wearing it.
In reality, the parachute is built-in to the ejection seat, and it would not be on their back upon landing after ejecting.
I would recommend adding a small backpack instead, to act as a survival kit should someone eject and continue on the ground.
