He stated that the ligtlt waa as large ati a basketball and \men it passed over the station it was noted that there were two smaller lights anrearing to the rear ani the sides of the main light. These s maller lights were of lesser intensity. A vapor trail followed the object.

Duration of si~1,ing. \vas flight smooth and constant, speeding up or slowing down other than the noted explosion. Color? Estimated. speed or distance travelled, esti.rnated altitude, possible sound associated with object? Have observers ever witnessed a fireball? How was 7-10 degree elevation determined?
