A large risk of damage to the cervical vertebrae of a pilot with a relatively low body mass appears at the time of opening the parachute. In this regard, the Pentagon initially decided not to allow pilots weighing up to 61 kg before piloting the F-35. Subsequently, the developers were sent a wish aimed at changing the mechanism of ejection.
New improvements will add to the cost of the entire project about 2 billion more dollars. The total amount of the project to create aircraft F-35, which are already produced in small batches, but constantly find defects and flaws, already exceeds 100 billion dollars!
Only the helmet of the pilot of the F-35 aircraft is estimated at an average of 700 thousand dollars. The helmet has a system for duplicating information from sensors and monitors of a combat vehicle for the convenience of controlling the aircraft and targeting it to the target.
