2 high altitude objects perform amazing maneuvers4th of July watching the fireworks we were naturally looking at the sky. I witnessed a bright object that resembled a satellite crossing the sky at a high rate of speed at a very high altitude. The object suddenly came to a complete stop before scooting off and stopping again in sudden short bursts. It made several sudden 90 degree turns and twists as it continued to move in short bursts of speed. It then stopped the erratic movements and sped off at a very high speed across the sky and out of site. Approximately 30 seconds after the first object disappeared out of site a second object that looked identical to the first object appeared from the same general location as the first object and performed a very similar series of short burst maneuvers as the first as it travelled the same path and like the first object eventually disappeared out of site leaving myself and my fiancé baffled as to what we had witnessed.
