The only video that I am aware of was shot by a kid it AZ. It is his vid that the time stamped pic came from. The California guy's pics are not public. He said he thought the things he saw were tiles. They were small and he had seen them come off before. The reason is that they donot hold the heat long and wink out.
The piece the kid saw, was not in that category. It was large and illuminated the contrail. It appeared rectagular to me, but not sure.
