“Following the inauguration of Donald Trump as the 45th President of the United States, a VC-25A or C-32A is made available to the outgoing President to fly the ex-First Family home. In this case, seeing as the Obama’s are going to be living in Washington DC for the foreseeable future, they will probably take the jet on a family vacation, and return home on a civilian registered aircraft. If the Obama’s are in the sky as President-elect Trump is sworn in, the jet’s pilots will actually request a callsign change in flight.”

I guess we have to look at timing of everything. Obama rode an old stagecoach to his inauguration so he wasn’t in the air. But Biden was, and so was Trump. Was Trump flying during the swear in? If so, did the call sign change during swearing in?
