There was none. It’s a non-event that’s only making the news because it involved Air Force 1. Spirit pilot missed a couple of radio calls, controller got frustrated and called the pilot out on it. Arguably unprofessionally and there is a chance the controller shortening the callsign to Spirit 1300 instead of Spirit Wings 1300 might not have helped. There is a lot of other chatter for other aircraft on frequency so we keep half an ear out for our callsign and kind of subconsciously tune out the rest. This means the first syllable doesn’t register but the second one and the numbers do. If that second syllable isn’t there, I could see why the calls got missed. A spirit pilot would have to chime in though as to how often they get called spirit vs spirit wings.

Anyway, once the spirit pilots heard their instructions they complied with it. It was an ordinary radar heading/traffic advisory that happens every day. And calls get missed everyday because we often have to split our attention between the radio and what’s going on inside the flight deck.
