Two pilots at Air Midwest claimed they saw unidentified flying objects when they were heading to Gloucester earlier this month.
The company reported the incident on Facebook and the post soon attracted the attention of many interested parties, with the company going on to provide detailed information about the UFO incident:
They wrote: "There has been a lot of interest in the fact that our pilots observed 'UFO's' last night during night flying exercises... so here is a brief summary of the situation."
"Two of our aircraft were conducting night navigation exercises to the south and south east of our home airfield.
"At approximately 20:15 one of our aircraft was tracking south towards Gloucester at 7000ft after leaving the the Birmingham air traffic zone.
"At the same time one of our other aircraft was also tracking south towards Gloucester at 4000ft when both aircraft observed one red and one orange lights in the the sky south of Gloucester.
"Our aircraft approached the lights on an interception track but were unable to gain on the objects as they appeared to move further south of Gloucester as our aircraft approached. We were unable to identify the lights.
"One of our pilots filed the following report on the event - 'I observed Initially 2 large square orange lights. One on top of each but slightly off set however there was a gap in height between them.
"'The top object was constantly orange. The lower one occasionally flicked white but majority of time was orange. In addition to that on 2 occasions I observed 5 orange lights but that was momentary.
"'I initially observed them when leaving Birmingham control zone. I thought they were just south of Gloucester and definitely a lot higher then us. We then climbed 5000 ft and they seemed level at that height and stationary.
"'As we approached Gloucester came apparent they were now further south maybe beyond Bristol even as far as Weston super-mare but directly south of Gloucester airport.
"'On our return leg up to EGBO (our home base) by Worcester we climbed 7000 ft and commenced a turn to observe the lights. At this point they seemed lower than us in the same place and stationary.
"'I have no idea what these objects were.'
"That is all we can say on the matter. Night glow balloons? But unlikely as these do not move very fast at all. So what they were? We have no idea. An interesting event."
In a further update Air MidWest wrote: "We are all pretty amazed here at air midwest by the interest in this post.
"But we must clarify we are not claimed we encountered an extraterrestrial situation.
"We encountered unexplained airborne lights that defied our normal expectation of standard aircraft or meteorological activity...
"We considered it could be night glow hot air balloons but we are not aware any any such activities taking place and the objects observed seemed to move from their original location to another with a rapidity not in line with balloon activity.. but of course the apparent changes of location could have been an optical illusion due to night effect.
"In conclusion our pilots, both senior flight instructors and highly experienced commercial airline pilots with over 25,000 flying hours between them, together with there crews observed airborne lights the nature of which they were unable to identify.
"For this fact alone we obviously can only describe the observations as 'Unidentified Flying or Airborne Objects'. Hence referring to them as UFO's, as that is what they were.
"We have no idea as to the origin of the objects and as yet we have not yet come across any standard explanation for what the objects could have been.
"We look forward to any information this week that could offer a suitable explanation for what our crews observed. Many thanks for your interest - Air Midwest."
