Hi
Just a note cause I’m a pedantic mood
Airforce 1 denotes a USAF plane the president is on – the VP gets Airforce 2 – don’t know what the wife gets.
If no Pres on board the 74’s revert to “normal” callsigns – I think
I did look it up on
http://www.milaircomms.com/mil_callsigns.html to see if my thoughts were somewhere near right – but I’m sure someone out there can explain the use of this call sign in DETAIL
