A series of security failures at an American airbase in Great Britain allowed a man with a teddy bear on his chest to drive around barriers and almost get into a helicopter.
An official investigation by the USAF into the incident has now revealed a catalog of blunders that forced the safety of all American air bases.
The report revealed how the mentally ill man gained access to the base by driving through an opening between a gate and access barriers, and a roadblock did not stop the right vehicle.
Kites let the intruder go through a checkpoint after he accidentally interrogated a lieutenant colonel in a similar black Volvo twice.
The RAF Mildenhall security breach on December 18, 2017, saw 11 shots fired at the vehicle by officers armed with pistols and guns while the driver was on his way to two Osprey heli planes.
When the unnamed man stopped at the American airbase in Suffolk, he showed a British passport and asked to speak to the president, the report said.
He managed to get to the airbase by driving between pop-up barriers and a fence through an opening that was created when a lamppost was removed to give joggers more space.

Because he thought the teddy bear could have been a suicide bomb, the runaway vehicle was rammed into the helicopter plane when the driver attempted to board the plane via an access ramp.
When he stopped at the base, the driver stated that he was from the secret service because he was approached by a pilot guarding the entrance, but did not provide any documentation to prove this claim.
After being told that he did not have the correct papers to access the base, the suspect grabbed the two-foot brown teddy bear on his chest and started rocking and celebrated, according to Air Force times.
The intruder managed to drive around the barriers, dragged a kite over the sidewalk and rode over active runways under the wings of two C-130 Hercules planes.
He then tried to drive up the driveway of a parked osprey before a pilot from a security team in a car rammed the intruder's vehicle and pushed it against the helicopter.
The man was arrested on suspicion of criminal offense and criminal damage and detained under the Mental Health Act, but does not appear to have been charged with the incident.
When the driver was approached at the entrance before stepping on the base, he asked: "This is a matter of national security, I have to speak to the President & # 39; and then slowly drove his black Volvo forward.
According to documents obtained in a Freedom of Information request, he was instructed to stop the vehicle, but instead accelerated the pop-up barriers.

The American airbase was closed immediately after the vulnerability in December 2017
This was due to a serious error in the gates, which left a gap of nearly eight feet between the gate and a fence after a street lamp post was removed five years earlier to create room for joggers, the report found.
He then turned west on Squawkin Hawk Highway and tried to enter the airport for the first time after about half a mile, but was blocked by a locked gate.
The base was immediately locked with security forces trying to respond, with some leaving their posts partially unguarded, according to reports.
A lieutenant colonel driving a similar black Volvo was stopped at a roadblock and interrogated twice by base pilots, but the intruder was not stopped until the confusion between the two vehicles was discovered.
Two airmen tried to block the intruder's vehicle and one tried to switch off the engine by reaching in, but the man accelerated.
Convinced that the teddy bear is a suicide bomb, three officers opened fire with their service pistols, sailed through the car with bullets but failed to stop the vehicle.
The driver & # 39; seemed to be mentally disturbed and & # 39; & # 39; was wrong & # 39; & # 39 ;, according to witnesses in reports published by researchers.
At one point a staff sergeant tried to grab the frame of the vehicle, but was dragged over the sidewalk.
He let go when he realized that the man was on his way to a base vehicle and when he got up his gun fired at the intruder.
After the incident was investigated by the USAF, security was strengthened on all its bases. Depicted RAF MIldenhall in the days following the 2017 incident

Brigadier General Andrea Tullos, then the director of the Air Force security forces, said the incident has urged the entire US Air Force to see how it approaches basic security.
He told Air Force Times: “It was a kind of wake-up call for us. This remains a studied case for us for years. Hopefully we don't have another one.
& # 39; The Mildenhall case caused us to inspect every access point for the installation in our entire air force that we own as a service, total force, guard and reserve, all of them.
& # 39; It made us look at many of our tactics, techniques, and procedures to say, why did this happen instead of this? & # 39;
According to a Force Review Board use that investigated the incident, a total of 11 shots were fired at the driver during the 20-minute infringement.
The investigation showed that the four officers used deadly force to try to arrest the driver.

A & # 39; Tiger Team & # 39; met to investigate the security breach and discovered errors made by the base. Some officers of the security forces prevented them from being & # 39; less than level I threat & # 39; to understand.
Mildenhall & # 39; s installation defense plan was not in compliance with air force regulations and patrols of the security forces were not posted in the right areas, reports from the investigation team were reported to contain.
RAF Mildenhall is ready for closure after the US said it would relocate its activities from there to Germany. The site was previously a potential target for terrorist attacks.
In May 2016, Luton delivery boy Junead Khan, who was planning to attack American soldiers outside RAF Mildenhall, was imprisoned for life.
Defense Minister Sir Michael Fallon then said in November 2016 that RAF Mildenhall was one of the 56 locations of the Ministry of Defense that were intended for closure.
The base, to be closed in 2022, is the home of the 100th Air Refueling Wing of the US Air Force and the 352nd Special Operations Wing.
