At 10:55PM radar contact occurred again, the URE was 30 miles east of Bentwaters moving west at an apparent speed of between 2,000-4,000 mph. The URE disappeared 2 miles East of the station and "immediately" appeared on scope 3 miles west of the station. It then disappeared entirely 30 miles west of the station. It is interesting to note that this URE appeared to be on the same course as the third contact and depending on the radar operators definition of "immediately" (as in blinked off and back on in the same sweep) then the speed would have been around 18,000 mph, or around Mach 25. The official Blue Book report estimated the speed lower, at 12,000 mph. Now at this point in this ongoing anomalous saga someone at Bentwaters called an operator at Lakenheath radar station and asked "if they had any 4,000 mph targets". The caller from Bentwaters also stated the control tower at Bentwaters had reported seeing a " bright light passing over the field from east to west at terrific speed at around 4,000 feet altitude." Now at this same time a pilot of a C-47 flying over the station at 4,000 feet reported "a bright light passed under his craft moving east to west at terrific speed."
Accordingly the Lakenheath radar supervisor had all controllers start scanning the scopes using MTI, or a moving target indicator, which eliminated all ground clutter, or ground returns.The operators soon discovered a stationary echo about 20-25 miles southwest of Lakenheath. It is interesting to note that the radars should not have picked up the target because it was not moving, but they did. Here is an interesting note on why they may have still picked up a stationary target:
A vibrating or rapidly rotating target will show up on MTI radar even if it is not otherwise in motion.

It then began moving once again in an instantaneous acceleration in velocity to 400-600 mph in a north, northeast direction. Local Air Force command was notified and kept appraised of the developing situation, which included the URE making several linear direction changes at around 600 mph with no speed change apparent in the directional changes. The changes varied between 8 and 20 miles in length with stationary episodes of 180-360 seconds (3-6 minutes) in between. It is also note worthy that there were several observations at Lakenheath at this time, including multiple site radar AND visual conformations of the objects instant acceleration and abrupt stops. At about 11:50PM the RAF (Royal Air Force) scrambled a de Havilland "Venom" fighter jet to investigate.

The case here differs in the British version and American (Blue Book) version in a few parts. The first difference is the location of where the jet took off from and where contact was made with the UFO. According to British reports the jet was launched from a field near London, which is 30-45 miles southwest, while the USAF report states the jet was launched from Waterbeach RAF station, which is only 20 miles southwest of Lakenheath. The second difference is the fact that the radar control supervisor at Lakenheath stated that the Venom was vectored to the stationary UFO (the fifth contact) at about 16 miles SW of Lakenheath and that was the only contact with the UFO. Now according to Blue Book "the jet flew over Lakenheath and was vectored to a radar target 6 miles east of the field. The pilot then advised he had a bright, white light in sight and would investigate. At 13 miles west of Lakenheath he reported loss of the target and light." This statement implies that the pilot had both a radar lock and visual sight on the UFO. "Lakenheath then vectored him to another target 10 miles east, the pilot advised target was in sight and he was locking on." Now in the timeline of things this new target would be classified as the "fifth contact", this one occurred both on the ground and in the air however. The watch supervisor at Lakenheath does agree with this fifth hit, except for the distance from the base. After these discrepancies everything else matches in both Blue Book and British accounts.

The stationary UFO was at an altitude 15-20,000 feet and about 16 miles SW of the base. Shortly after the new vector was given Lakenworth told the pilot the URE was half a mile dead ahead, the pilot then radioed, "Roger...I've got my guns on him." The pilot was referring to a radar fire control system, the pilot told the USAF later that the "URE was the clearest target I've ever seen on radar." There was a brief pause after the pilot radioed the lock, then the pilot radioed Lakenworth asking "Where did he go?", "Do you still have him?". Lakenheath then radioed in saying the UFO had made a swift circular movement and was now BEHIND the aircraft! The pilot then confirmed the UFO was indeed behind him and that he would "try to shake it". The pilots numerous maneuvers to shake the unknown aircraft were unsuccessful, Lakenheath said that there was a distinct radar echo behind the echo of the jet, indicating that the separation was greater than 500 feet. At this time, still unable to shake the UFO of his tail the Venom pilot requested assistance. After around ten minutes the first pilot radioed in, reportedly sounding very scared, saying he was returning to base because his fuel was low. He asked if the craft was following him and was told by Lakenheath that it did for a short distance then resumed its stationary position.
"He tried everything. He climbed, dived and circled. But the UFO acted like it was glued right behind him. Always the same same distance, very close."
For 10 minutes the pilot tried to shake off the object. Those on the ground could "tell from his tonal quality that he was getting worried, excited and also pretty scared."
Soon after he turned back to base as fuel was getting low.

The second Venom was directed towards the last position of the UFO but before he got close enough to the object he reported engine malfunctions and stated he was returning to base. The following is the pilot to pilot conversation monitored by the radar control:
Number 2: "Did you see anything? "
Number 1: "I saw something, but I'll be damned if I know what it was."
Number 2: "What happened?"
Number 1: "He - or it - got behind me and I did everything I could to get behind him and I couldn't. It's the damnedest thing I've ever seen."

Here is the information taken by Blue Book personal regarding the Venom-UFO encounter:
d) [Description of flight path and maneuvers of object(s)] Flight path was straight but jerky with object stopping instantly and then continuing. Maneuvers were of the same pattern except one object was observed to "lock on" to fighter scrambled by RAF and followed all maneuvers of the jet fighter aircraft. In addition, Lakenheath RATCC observed object 17 miles east of station making sharp rectangular course of flight. This maneuver was not conducted by circular path but on right angles at speeds 600-800 mph. Object would stop and start with amazing rapidity.
Lakenheath Collaboration
The pilot of Venom one said he did have a radar gun lock for several seconds so "there was something there that was solid." Following the chase the UFO did not immediately leave the radar scope, according to the night supervisor:
The target made a couple more short moves, then left our radar coverage in a northerly direction -- speed still about 600 mph. We lost target outbound to the north at about 50-60 mi., which is normal if aircraft or target is at an altitude below 5,000 ft (because of the radiation lobe of that type radar [a CPS-5]).
The time of the loss of contact was given by Blue Book at around 3:30AM. It is important to note that the radar supervisor stated "The speeds that night were all calculated based on the time and distance covered on radar." Additionally he said, "This speed was calculated many times that evening."
