When people are making models of it and writing magazine articles about it?
I think you are overly infatuated with the word 'conspiracy' and you're applying it inappropriately. You want it to be both a pejorative pronoun and a subjunctive adjective simultaneously without differentiation.
These are trivial compared to the public safety implications of an unexplained missile launch off the coast of America's second most populous city. What an alarming sight for anyone who happened to look towards the sunset during those ten minutes or so. Don't you think the government owed the people of Los Angeles an explanation?
Except of course that it wasn't an alarming sight, since to most Angelenos the contrail looked exactly like what it actually was -- a typical contrail, the kind they see all the time off their coast. It was only for people within an extremely narrow viewing angle -- directly in front, where foreshortening might make it seem to travel upwards -- that it would have looked remotely interesting.
Nice avoid on the LAX webcam pic, btw. If you can't deal with it, just ignore it, right?
