A rocket launch from a Southern
California Air Force base generated a fiery contrail that could be seen
all over Los Angeles Friday and had some social media users preparing
for an alien invasion.
SpaceX's Falcon 9 rocket lifted off from Vandenberg Air Force Base at
around 5:30 p.m. local time. Its mission was to send 10 communications
satellites into space.
But it was
the rocket's contrail of water vapor, illuminated by the sun, that had
seemingly all of Los Angeles looking up in the sky.
The Space Archive website noted that the Falcon 9's "bright flame should
be visible over a wide area." It added that the contrail "could be
impressive" beginning two minutes and 12 seconds after launch.
Users on Twitter posted images of the
contrail's weird shapes, with some speculating they were caused by
extraterrestrial visitors.
