Yes both have served as Air Force 1.
Back in the 70’s I flew a 747 to England, and a 707 back, I recall watching a 747 pass us on the way back, but the main thing I remember is that my feet got cold because the outside temperature penetrated to the cabin. There was a stream of hot air blowing on my head, and I was wishing I could reverse my position and put my feet up in the warm air.
Another time, I flew a 707 on business into Newark on a blustery day. We did a big, low, slow banking turn on the approach with the wings flapping like a bird and the engines nodding and weaving drunkenly. Quite a sight. Some guy near me was yapping up a storm of business talk with his seatmate, pretending not to notice. Suddenly he fell silent for a second, then exclaimed, “This tub’s gonna have trouble making it in!”
I will admit a certain fondness for the thing, though.
