In early 2007, radio enthusiasts near RAF Lakenheath, England picked up on a bizarre conversation shared between to American F-15 pilots, who appeared to be chasing “an unknown”. “I had a radar hit and it was swinging at what looked like 30 knots,” one pilot tells the other. “There was something there… it didn’t look like a bird, it looked like a rock to me.” Initially the two pilots attempt to avoid the object, the first warning the other pilot that he has “no idea what it was, but basically just heads up. Try to stay away from 17,000.” However, once it appears on their radars again, the two pilots begin to pursue the object in an attempt to get close enough to see what it might be.

In the video above (which is actually a compilation of stock aircraft footage put to audio supplied by, you can hear the confused banter between pilots as this strange, tiny object hurtles back and forth around them. At one point, one of the pilots actually says “I don’t think it’s falling,” comparing it to some sort of debris or meteorite. Instead, it appears evident that the object, described as “Something very small, some very small black object,” is indeed flying near them at an altitude of about 17,000 feet. What could this strange object have been?

  1. I think the most interesting parts are where both of them call it a “he” and not an “it”.

    Who would call a rock a “he”?

  2. Thanks for posting this… the most impressive thing for me is the very refreshing attitude of these pilots… the intense curiosity they show in dealing with this wonderfully unusual object and spending time trying to find out what it is is really quite nice.
