But (as mentioned above) if spacecraft are designed for negative (outward force) pressure it might have difficulties resisting positive (inward force) pressure of submergence. It also needs to get to the Earth and land without being detected. This might be difficult with all the military radar around the globe. | |

If they're biological aliens from a planet with an atmosphere similar to Earth, space travel requires only dealing with a pressure difference of around -15psi. Not too difficult in comparison. | |
