No kidding, it did not exist 50 years ago, you did something 50 years later going to the moon- and then developing a docking tech that is the first but not because it was innovative. Rather because nobody else cared for it. It does not make you guys any space leader, where you can taunt the Indians. I mean for Pete's sake - they went to Mars before you guys
and then, you are circa 50 years behind our accomplishments. quit bragging wu mao when you come from a house of cards
AND, you do brag here all the time- never missing a moment to push bigoted and racist taunts, putting others down (mostly Indians and Americans).
ROFL 50 years later than us to the party and you are bragging about a docking tech that nobody cared about.
