This is one of thousands of ufo videos taken over the last several decades by American military aircraft. What we see here is one of these ufo videos taken by American F-15 fighter jets reportedly pursuing an unknown aerial object, more commonly known as a ufo. The fighter pilots conversation is of course recorded on all flights and the lead pilot is describing the ufo as an object he is following at seventeen thousand feet over the U.S. Air Force base in Lakenheath, England. His wingman is shooting the ufo video with his F-15 gun camera while lagging behind the pursuit pilot. You can hear from the ufo video conversation one of the pilots refer to the fact he has "no joy." What this means is his F-15's weapons control panel is telling him the missiles his plane is carrying can not acquire a "lock-up" on the unknown aerial object. This is a very strong indication the object in this ufo videos case is NOT another airplane. Many ufo videos recorded by military aircraft have reported this very same occurrence which leads one to seriously consider the fact this might in fact be a legit case of an unknown flying object caught on tape as a ufo videos case.
