Totally caught it by accident. I was driving Rt 16 in Portland around 3pm and it flew right overhead in front of me. Kind of caught me off guard because it looked like a passenger plane flying super low. So low you could see the NASA tail logo. I had to pull over and open the flight app to see what the heck I just saw. It was the NASA DC8 airborne science lab flying at a super low 1400ft!
