Fast moving (over 30 miles in 10 minutes), sharp 90 degree turns, solid light with no flashes.

Fast moving object overserved traveling over 30 miles in roughly 10 minutes, smoothly through the sky.  Not high altitude so I’m ruling out a satellite.  Solid white light.  No noise, no flashing lights so I’m ruling out drone or GA.  90 degree sharp turns.  Observed flying above Mason, NH into Manchester and then down to the Westford/Groton area.  Observed from a location with long distance views and with over 5 witnesses.  People stopped their cars and got out to view.
