Anyone looking at these photos would assume they came from a satellite or airplane. They were actually shot by an engineering student with an inexpensive camera and a balloon. About $320 based on todays currency rates. He used GPS to track and recover his equipment after it returned to earth.
Yes. I read that the MIT group coordinated with U.S. air traffic control. There was also a Romanian guy who sent a lego space shuttle into space on a weather balloon (with a camera). He had so much difficulty with Romanian air traffic control that he moved the launch to Germany instead.
