Why is the Snow Eagle helicopter of China Antarctic expedition an old Ka -28? I think Russian children's planes are very unreliable.

Think about it, Mao killed Napoleon and Hitler that winter, and the card 28 they made was obviously suitable for ice and snow. K28 has no tail rotor, so it takes up less space on board.

Moreover, there are only 20-30 Black Hawks, which is not enough for Luhang's own use, and accessories are hard to buy.

There is no such thing as an all-weather plane. The weather is so bad that no plane can fly.
