Answer 1

They had been sending sounding rockets, probes, and experiments into space since basically the end of WW2. The German V-2 actually left the major part of the atmosphere when bombing England.

Finally, they actually used modified weather balloons to send Joseph Kittinger to the edge of space to test a spacesuit. He held the record for highest free fall skydive until Felix Baumgartner broke it with Red Bulls help.
