FWIW
According to Business Insider, ‘top aviation journalist’ Jon Ostrower said via twitter that he was 100% convinced it was a jet.
From website Instapundit.com:
“Reader Larry Rachman writes: “Sounds like those aliens from that faked oil rig explosion are finally heading home. Godspeed.””
Also from website Instapundit.com, a letter
from Cliff Beach who says he was in the army - missile defense for 22 years, says the following ( summary quotes):
“So if this was a missile, the DoD knows it was within a few seconds.”
and
“Adding to the belief that it is unlikely DoD is withholding info is the fact that DoD has no pubic relations staff sitting around ready to confirm that a passenger jet was flying in the sky near our west coast. They probably have not the foggiest idea how to absolutely confirm that jet A caused contrail B seen by public C and ensure it is believed by conspiracy theorists D, E, and F. “
That’s reassuring to think that the DoD has no idea when an aircraft comes with 35 miles of one of our biggest cities. Not to mention numerous military bases in the area.
If that's really what he said, then Jon Ostrower is a moron.
