I have a few nominations to test out this single-person rocket into space. A company is designing a teeny rocket that will fire the rider into the wild blue yonder and (hopefully) back again.
Copenhagen Suborbitals made a stand-up rocket with a see-through nose cone called HEAT, or Hybrid Exo Atmospheric Transporter, and it can send a human into space at forces around 3g.
Implications - The rocket was made by a Danish aerospace startup to test out the company's new rocket engines. The featured video shows HEAT in action as it blasts a powerful flame of fire. People can be heard cheering in the background when the fire condenses. You would certainly have the fastest ride on the block with that thing attached to it!
