The most expensive plane crash in history, costing $2.5 billion. On February 23, 2008, a U.S. B-2A stealth bomber (No. 89-0127) malfunctioned while taking off from Anderson Air Force Base in Guam, and then slid and fell to the ground. The plane was burned down, and 2 pilots ejected to escape. Instantly vanished into nothingness. China moulding rubber Manufacturer
After investigation, the cause of the accident was the failure of the attitude sensor (it rained and entered the water), which provided wrong data to the flight control system. Because the B-2A bomber adopts a rare tailless flying wing layout, the aerodynamics are super complicated, and it is almost impossible to carry out artificial poles. Operation, all flight actions need to be completed with the cooperation of the computer system.
The biggest specialty of the B-2A is its advanced stealth performance. The previous heavy bombers were intercepted by enemy air defenses. In fact, although the B-52 type aircraft dispatched a total of 126,615 times in the Vietnam War (June 1965 to August 1973), dropped 1.6 million tons of bombs, and completed the combat mission as a strategic heavy bomber, it was not in the air defense. The strict Vietnam capital Hanoi and other places suffered heavy losses during bombing operations, and a total of 31 B-52 aircraft were lost in the war. The Vietnamese army fired 1,000 radar-guided SA-2 surface-to-air missiles over North Vietnam, and 18 B-52s were shot down by the missiles. China moulding rubber Manufacturer
According to statistics, over the past 60 years, the number of U.S. fighter jets, helicopters, bombers and other manned aircraft that have crashed due to wars, accidents and weather has exceeded 10,000. From 2013 to 2019, the accident rate of U.S. fighter jets, helicopters, bombers and other manned aircraft was as high as 40%, and the number of crew fatalities soared to 171. In 2018 alone, U.S. military aviation fatalities hit a six-year high, with 38 pilots or crew killed in crashes.
There may be the following four reasons for the soaring accident rate of U.S. fighter jets.
First of all, most of the fighter jets of the US Navy and Air Force were designed and manufactured during the Cold War. The average service life of fighter jets, bombers, transport aircraft and armed helicopters is very long, and the aging of the airframe poses a security risk.
Second, pilot training time is less. Since 2013, the U.S. military’s military expenditure has been greatly reduced. In order to save military expenses, the five major U.S. military services have shortened the training time of pilots, resulting in some pilots having poor flying skills. The average training time of US Air Force pilots is about 300 hours per year. The reduction of US defense military spending has reduced the training time of ordinary pilots to 150 hours.

Again, America has more wars. Because the execution of combat missions is completely different from training, it may be hit by enemy artillery fire, and at the same time, the combat intensity is relatively large, and there will be more accidents.
Finally, the technical sophistication of some of the new aircraft has some major flaws. For example, the famous F35 fighter has 13 serious defects. The cabin pressure of an F35 fighter jet would suddenly rise, and on nights with few stars, the night vision camera would sometimes show a “green light”.
The above points may be the main reasons for the recent series of serious flight accidents in multiple branches of the U.S. military. Although the U.S. military has the world’s largest military ranking, it still faces many practical problems. China moulding rubber Manufacturer.
