Good spot, Mr G!
A quick search reveals that N718BA was en-route Charleston-Everett this morning:
Great Circle Mapper produces this track:
I'd hazard a guess that this is the aircraft you saw.
I found another Dreamlifter which was on the way to Anchorage from Charleston but very early in the morning, probably barely light.
Anyway, never mind about your aircraft spotting. What about the chemtrails?
