Last October 12, a UFO was spotted trailing a jet over Amsterdam. A video of the sighting was posted on YouTube with the title "UFO Sighting Report 20141012: Amsterdam October 12, 2014, 09:36 GMT" by the YouTube channel, theInterzone.

According to UFO Sightings Daily, the UFO that looks like a blinking object, first entered the trail and then stopped there for a few seconds. It then exited the trail. Scott Waring, who posted about the sighting on the site, wrote that aliens were interested in things that fly that include things that cause pollution as well.

The video was uploaded on YouTube last October 12 and since then has been being viewed many times. It has garnered around 50,000 views in a matter of three days and has attracted about 190 comments. The channel that uploaded the video has posted many other videos of sightings of UFOs in Amsterdam over a span of four years. Here is a look at one of the comments that had been posted by YouTube user, timbrebender.

timbrebender: So, the videographer just happen to be filming random airliners that day. Were they purposely looking for the "chem-trails?" I guess it doesn't matter, but one thing about extra terrestrial visitors does. The UFO is indeed that to be sure but that does not necessarily mean it is of extra terrestrial origin.

In his comment, timbrebender also wrote that one should think about the Canis Major Dwarf Galaxy that is 25,000 light years away from the Earth and also the closest to Earth. He said that if any civilisation visiting the Earth would take at least 25,000 years to reach us even if it were travelling in the speed of light. He said one factor that had to be considered was that the universe was still expanding.

He continued that it wasn't possible for any visitor to have developed super luminal travel, which is basically travelling faster than the speed of light. He said it wasn't impossible but questioned why it would travel such a long distance and not make contact with those on Earth. He said that it wouldn't worry about those on Earth as a threat because its technology would be superior than that of the people on the Earth. He was almost certain that there was life on other planets as well but didn't think that aliens visiting made sense.
