ALIENS? USAF jets were scrambled to see what the UFO was.
An unknown aircraft was spotted flying through well-monitored air space above Oregon state.
Witnesses were left questioning where the jet may have come from and what it was doing.
Military officials have been unable to identify the plane’s origin or even destination, after it vanished and they were not able top trace it, Dailystar.co.uk reports.
Oregon borders Nevada, which is home to the mysterious and top-secret Area 51 US Air Force base where tests are conducted on experimental craft.
Air force F-15C interceptor fighters were launched in response to the sightings, according to local news reports.
North American Aerospace Defence Command confirmed it had been asked by the Federal Aviation Administration to help track the unidentified aircraft flying at heights regularly used by commercial aircraft – 35,000 and 40,000ft – on October 25.
Fighter jets were scrambled from Portland to investigate, but failed to find anything.
No flight plan had been submitted for the unidentified craft and no identification transponder was active.
The craft was not transmitting collision avoidance signals.
Air traffic control stations were reportedly having difficulty following the craft on radar.
I live in Eugene and I see UFOs all the time. Whether it be day or night. I could tell some interesting stories to say the least.
The F-15C Eagle interceptors have some of the most advanced combat search and tracking radars in the world.
The incident left people wondering what the object could have been.
In a debate on Reddit, some users speculated the object could be an alien UFO.
One posted: “A literal UFO.”
Another said: “I live in Eugene and I see UFOs all the time.
“Whether it be day or night. I could tell some interesting stories to say the least.
“Eugene seems to be a hot bed of activity… Keep your eyes on the sky.”
A third added: “Central Oregon here. I could say the same thing about the things we see over here. Definitely weird.”
A fourth Reddit user, who claimed to have been a pilot in the air at the time, said: “Strange! My theory is they were running drugs to Canada. No news yet, not that I could find.”
He described how airliners had been asked to help track an unknown white-coloured aircraft visually for up to 30 minutes as air traffic control radar was having difficulty getting a fix.
While it was in sight of various airliner crews, it was apparently never close enough for its type to be identified.
“The last aeroplane to see it had to descend into Portland and lost sight of it.
“The fighters were scrambled out of Portland but flew around for a while and did not find it.
“And that’s that.”
