Time is within about 5 minutes or so. Event occurred during the last piece of a Virginia Orchestra concert on Yorktown waterfront. Many people sitting on the hill by me — facing toward the orchestra saw it also — about twice as high as the Coleman Bridge from my perspective. It was very quick… only a second or so. I’m a BSA Astronomy MB Counselor, and a retired USAF C-130 Navigator from back in the days of celestial navigation and a bit of a NASA Space buff from living around many people from NASA Langley.
