A bright object that streaked across the Texas sky during the day April 4, originally believed to be a meteor burning up as it entered Earth's atmosphere, was actually a flying jet and its contrail, a NASA scientist has confirmed.
Local news stations reported that the bright object was a fireball (an especially bright meteor) and Bill Cooke, head of NASA's Meteoroid Environment Office, initially said it was indeed a fireball, and more evidence of the mysterious and unexplained observation that there are more fireballs in the spring than other times of the year. However, other experts argued that the Texas fireball was actually a jet contrail reflecting the glow of the setting sun, making it appear fiery.
Cooke has agreed. "Reviewing the video, it does appear to be a contrail," he told Life's Little Mysteries. "There were sightings of a daytime meteor April 2 but this video is not of a meteor/fireball. Different event."
The April 2 daytime fireball — a rare event, as a meteor must be at least one yard across for its atmospheric entry to be visible during the day — was seen by thousands of people in New Zealand.
