I think the Osprey is good, the reason there are a few accidents is that Japan uses AI after purchase, and it is good for operation.Japan's maintenance ability is the best in the world.Japan also uses a new engine and can make a jet, it is fast and has a range of 10,000km, and the Osprey has a propeller rise. Weak, with 10 fully armed members and just over 1 ton. With two newly developed engines, the thrust is 30 tons, the engine weight is less than 4 tons, and if the aircraft weight is 30 tons, it can surely carry 15 tons of cargo 14 times more, and if it takes off from the runway, the total weight can be expected to be 66 tons, and the cost will be reduced by producing 10,000 engines. The ultra-light and powerful engine is easy to use, and the development has been carried out to produce 10 times more thrust, 100 times more thrust, and 1000 times more thrust.The dream is big that the ultra-light and powerful engine can be used all over the world and can be mass-produced to significantly reduce costs.
