钱学森当年是如何“冲破重重阻力，毅然回国”的？
只有极少数中国人知道Roger Yonchien Tsien 是谁，虽然这个美国人已经轰动全球，他的事迹也让许多中国人引以为傲，但中国人所熟悉的只有他的中文名字———钱永健。2009年度诺贝尔化学奖得主，又一个华裔。
但是浙江大学吴越钱氏研究所所长李最欣说：“除了华裔血统，钱永健跟中国实际上并没有太多关系。他虽然一年前回了中国一趟，在杭州也转了转，但他却是美利坚合众国的公民，不会说中文，接受的也是西方的教育。”但是，钱永健却跟中国一个延续千年的名门望族有关，《百家姓》中的“钱”氏。他是中国著名科学家钱学森的堂侄，从族谱上来说，他是吴越钱氏的后人，钱王钱鏐第34世孙。而让人吃惊的是，历史上吴越钱氏人才辈出，以近代为例：钱穆、钱学森、钱伟长、钱三强、钱钟书、钱正英、钱其琛……都是吴越钱氏的后裔。
李最欣介绍说，据目前的粗略统计，吴越钱氏的后人中，仅当代国内外科学院院士以上的就有一百多位。钱家子孙遍布世界五大洲，除此之外还出政治家、文学家……说他们是名门望族可谓实至名归。
钱学森的堂侄（好奇怪的亲属关系）——获得诺贝尔化学奖的钱永健就披露了当年钱学森是如何回国的。
钱永健说：
My father's cousin was quite a famous engineer (H.S. Tsien). He was the head of the ballistic missile program for the People's Republic. It's actually a strange tale. He was at Cal Tech as an aeronautical engineer, but then got in trouble in the 1950s because he had some communist links in his past. He was put under house arrest and then deported. Back in China, he started up the ballistics program, I guess partly because he was mighty pissed off at the US!

Quote from Aviation Week （摘自美国航空周刊）
"He was seeking U.S. citizenship at the time.
Apparently insulted, Qian first responded to the loss of his security clearance by trying to return to China, but he was stopped by the government, which wanted to keep his knowledge of U.S. secrets inside the U.S. Then both sides changed their minds. The immigration service sought to deport him, regardless of the fears of other agencies, and Qian tried to stay, apparently determined to clear his name.
Qian’s attempt to stay almost certainly proves he wasn’t, in fact, interested in working for China. By that time he could have best done so by going home with his expertise and U.S. secrets. Without a security clearance, it was unlikely he could achieve much for China by staying in the U.S.
The immigration service won its case against Qian, but the government still hesitated to send him back. After years in limbo, the scientist himself decided again to go home and sought help to do so from the Chinese government, which secured U.S. agreement as part of negotiations over Korean War prisoners.
His reluctant return was hardly a patriotic act, but that was, and still is, overlooked in the official Chinese view of history. As recently as 2003, the Xinhua news agency, recounting his story, reported blandly: “In 1955, six years after the founding of New China, Qian Xuesen returned to the motherland.”
It turned out that some of the U.S. fears of sending Qian back may have been exaggerated. First, the secrets that he knew were at least five years old by the time of his return, and that was an era of rapidly changing technology.
Second, no single scientist or engineer can have more than a fraction of the knowledge needed to design space launchers or missiles. So he could only be a leader, not a one-man rocket builder. Indeed, his role turned out to be that of administrator of the Chinese space program. Moreover, Chang wrote that in many cases he told his questioning comrades that the technical answers they needed had already been published; they needed only to look up the right book, often an American one."
