OK, maybe not orbital but how about sub-orbital, is that a possibility? How about a target missile for another system being tested? How about decoys? The possibilities are not so small.
Judging from the shots I saw, that’s the exhaust plume of a solid propellant rocket motor. The point of origin is either at sea level or from a subsurface launch. The trajectory is definitely that of a missile. The flight profile looks like either a cruise missle or SAM and not a ballistic missile.
The question is what do the FAA radar tapes reveal origin, course, and speed?
Then, who’s the responsible party?
