It looks like a missile, dozens of highly credible and experienced experts, have identified it as a missile...but you say it's a plane. Tell me the flight / plane that made this contrail.

It wasn't flight 808

nevermind, should always read the thread first! See a lot of folks pointing at UPS902, will check it out.

It was later determined that UPS flight 902 fit the facts better. It was beginning its descent for landing, and dropped out of the upper layer of the atmosphere where the contrail was forming thus clipping off the near end.
