Air Force One, painted blue and white, is the special plane of the President of the United States. It has an impeccable safety record and is considered as the safest plane in the world. In order to prevent accidents, two numbered "Air Force One" will fly in formation at the same time during each visit. "Air Force One" is called the most advanced aircraft in the world today, and its facilities are comparable to the White House. The American media said that there was "Air Force One" in the White House. For example, this plane has more than 4000 square meters of space. In addition to the presidential suite, there are oval offices, fitness centers and medical centers that imitate the White House.

Although "Air Force One" is just an airplane, as long as the president travels, except "Air Force One", supporting transport planes and helicopters must take off with him. These planes mainly carry the president's living and safety facilities, such as bullet-proof cars for the president. When Obama attended the G20 summit in London in April this year, there were 35 bullet-proof vehicles on the transport plane.

As a presidential plane, Air Force One has comprehensive security measures. It can defend against electromagnetic pulse generated by nuclear explosion and is equipped with advanced anti-monitoring equipment. In order to prevent enemy planes from attacking in the air, "Air Force One" is generally escorted by F- 16 fighters of the US Air Force when it takes off. After arriving in the host country's airspace, the most advanced fighter plane of the host country will replace the F- 16 fighter plane to escort until "Air Force One" lands safely.

■ Cars □ "Beast" is equipped with armor and weapons.

Obama's car is called "Army One", which was converted from a Cadillac limousine. The car not only has a unique bulletproof system, but also is equipped with advanced communication devices and life support systems.

According to the usual practice, the Secret Service always carries a presidential car on the "Air Force One" plane in case of emergency, whether it is necessary or not. Obama's trip is no exception. According to American media, the Secret Service took Obama's 2009 Cadillac extended luxury bulletproof car. This car was personally selected by Obama when he took office, and was dubbed "the beast" by bodyguards.

Of course, the most important thing in the presidential car is safety. It is reported that the protective performance of "Beast" exceeds that of infantry fighting vehicles. The bulletproof glass of its window is 55 mm thick, and the bulletproof glass of the whole car adds up to 2.7 tons. Only the bullet-proof glass on both sides of the driver's window can be lifted to facilitate the driver to contact the agent. All other windows are sealed. The body, underbody and roof of Beast are made of titanium alloy, high-strength ceramics and composite armor, and the cockpit is designed with pressurized seal to resist the attack of chemical and biological weapons. In addition, the "Beast" is also equipped with an electromagnetic jammer, which can emit powerful electromagnetic pulses, temporarily disabling explosive devices or timing systems within hundreds of meters. There are some light weapons in the car in case of emergency.

Once the American president's car is retired, it is mostly destroyed by throwing it into the sea, blasting, crushing or burying it deep underground, and it is never allowed to flow into the people. After the 42nd President of the United States left office, Bill Clinton asked the Diplomatic Security Bureau for Cadillac fleetwood, but failed to get the key back. The security department replied that he could clean the glass for Cadillac fleetwood, but he would not be allowed to enter the steel behemoth again.
