[4K] F35 Pilot reports "Squawk 7700"

The pilot of the F-35 Lightning II reported a squawk 7700.
Squawk 7700 is given when a pilot experiences problems with the aircraft and immediately makes a landing request followed by fire service assistance.

The pilot of the F-16 Viper reported an "hang-up".
A hang up means that a bomb has stuck when it should have been dropped.
In the video you can still see the bomb hanging under the right wing of the F-16 J-020 after landing, because of the safety protocol fire service assistance is required.

The ringing Bell you hear in the video is a traffic warning bell along the road on the airbase wich crosses the runway. So it's a traffic safety warning when there is flying traffic on the runway the traffic may not cross the runway.
