Puzzle: Yuri Gagarin was the first person to fly in space. Who was the first person to fly in space twice?
For the purposes of this puzzle, I adopt the definition of space flight used by the Fédération Aéronautique Interationale (FAI) and NASA: flight above the Kármán line, which is by convention defined as 100 km (330,000 feet or 62 miles) above sea level. This is the altitude where the Earth’s mean atmosphere becomes sufficiently thin that a winged vehicle would have to be travelling at orbital velocity or greater to develop sufficient lift to support its weight.
Please don’t just type this question into a search engine. That’s no fun and the odds are many of the results you’ll get will be wrong.
I’ll identify the first correct answer in the comments or, if nobody gets it, post the answer in a spoiler block to-morrow.
