After the scrubbed launch because of a "boat within the safety zone" and an apparent try to re-launch I witnessed a small red (maroon) object on a trajectory similar to the shuttle paths. It did not blink as would a plane's left wing light. This occurred after the mission was scrubbed. I saw, from my backyard in Edgewater, a maroon object at high altitude going NE in a straight line EXCEPT that it would suddenly accelerate to a new forward position in an instant. It did this several times. I have watched many launches but never saw anything like this.
