HS-14's callsign is "Lightning", which could cause confusion on one carrier. I know it bugged me for my first few months at Pax hearing the F-35 use it on the radio. I guess Ultra High Profile programs can just call themselves whatever they want.
Edit: shouldn't the F-35 get an animal nickname like most aircraft?
FIFY
Aren't animal nicknames considered no longer PC or some bullshit like that? Or maybe it was just patches with humanized animals... I can't keep up with who is getting offended by what lately.
