摘要
Every Sci-Fi movie shows our heroes traveling in futuristic planes straight into space. Not only is this a dream of space enthusiasts around the world but also rocket scientists who can actually make it possible. However, building a space plane is way harder than building a traditional rocket due to a variety of reasons. First of all, planes rely on the atmosphere to generate lift and their jet engines rely on oxygen to perform combustion. Given that space doesn't have either of these, scientists have to modify planes quite heavily to have them successfully operate in a vacuum. Aside from the atmosphere problem, space planes undergo extreme heat during various portions of their flight. Thermal issues proved to be one of the biggest shortfalls of the Space Shuttle, and this is still the case today. This video explains the various physical limitations of flying a plane into space and why building a space plane is nearly impossible.
