Contrails don't always form, it depends on the state of the atmosphere: temperature, humidity, etc, at the altitude of the plane. I'm told that as Australia is a destination, but not between other major continents, high altitude planes, and contrails are rare (lifeonperth.com/contrailsoverperth.htm ) I live under busy skies, and see a lot of high altitude aircraft. | |

| Apr 27, 2016 at 3:44 | comment | added | Andrew Thompson | The daylight fireball traveled from Utah to Alberta Canada in 100 seconds, a distance of approximately 1200 kilometers. That is around the same as the distance between Sydney (where I was) and Adelaide (half way across the continent). The object I saw did not go out of (visible to the eye) sight within around 10 minutes, so I think the answer to my question is: "The likelihood of it being debris from space is so close to 0 as to be effectively indistinguishable from 0". Thanks for the link. This is answered. | |

The compelling point you made (that I did not realize) was that such debris reentries are typically very short in duration. | |
