Returning from investigation of green fireballs in a Beech T-7, heading East at 90° and 190 mph at 11,500' altitude and 5,000' above ground, saw green fireball 30° to the left of their flight path, to the eastnortheast at 60° azimuth, at an estimated 2,000' above their flight altitude of 13,500'.
Which shot past them maintaining almost level flight until the end to the WSW at 240° azimuth when it seemed to burn out and drop suddenly with reddish-orange glowing fragments which lasted less than 1 second.
Later aerial search of the ground site in daylight found nothing.
