I asked a question about reaching space using non-rocket aircrafts on aviation.se and I found out that it may be possible to reach the space for a short moment and then a normal aircraft designed to fly in atmosphere would start to fall. Still, that would allow to reach a certain altitude. I wonder what use could that be. Maybe transporting some supplies to orbital stations? But then with the velocity differences, it would result in a crash.
xkcd illustration of such ascend:
Is there any use currently or theoretically in reaching out to space shortly without the ability to stay in orbit?
