你能想像在二战期间,英国即研制了能达到每小时1000英里的喷气动力的飞机吗。这种飞行速度在当时是不可想像的。然而,这个称为M.52的项目刚具雏形就被取消了。这背后到底有着怎样的原因?一些人原以为M.52项目是以前许多“秘密”战时项目之一。然而该项目实际是英国在第二次世界大战开始以后有计划实施的一系列大型科研项目的典型范例。 Can you imagine that during the Second World War the United Kingdom developed a jet that could reach 1,000 miles an hour? This flying speed was unthinkable at the time. However, this project, called M.52, was initially ruled out. What are the reasons behind this? Some people thought that the M.52 project was one of many former “secret” wartime projects. However, the project is actually a typical example of a series of large-scale scientific research projects planned by the United Kingdom after the start of World War II.
