UFO buzzed Endeavor/ISS complex.It is my routine during shuttle missions to leave a video tape running over night in my vcr. During the STS96 mission, this routine was followed, and I accumulated 8 6hr. vhs tapes of mission events. These 8 tapes covered the time period of about 23:00 to about 05:00 on the nights from May 30 to June 5, 1999. On the night of June 2/3, 1999, the usual procedure was followed for my part. At bed time, I inserted a blank tape into my vcr, and let it run over night. On June 8, 1999 I happened to be reviewing this particular tape. At about 4Hrs. 40 mins into this tape, one of Endeavor's payload bay cams was trained on one of Zarya's solar panels, when suddenly a bright pulsating object buzzed the space complex. I am in possesion of this tape and would be happy to show it to someone who could make use of it. Owing to the fact that this sort of evidence often disappears when it falls into the hands of government people, I will not part with it, however.
