Out There stories relating to "Contrail"

Yesterday, a strange contrail moved rapidly over New York. Now another one, similar to the one over the Pacific near Los Angeles on November 8.

If this object is high enough to form a contrail, it is moving at extreme speed. If it's low enough to be a very fast jet, then it wouldn't produce a contrail. Conclusion: despite what the newscaster say about it, t's displaying unusual flight characteristics. Grade B.
