Nobody has taken an aircraft around the circumference of the Earth nonstop. No airplane has the 30,000+ mile range that would be required to fly around the Earth without stopping. But the technical answer to your question would be the Space Shuttles, which did dozens of orbits around the Earth on their missions.
How long would it take a bird to fly around the world if it were able? How long will it take to fly around the world in a hot air balloon? an airplane? What model aircraft? Biplane, prop, jet, jumbo jet, supersonic, spaceshuttle, other? Which direction would the flight entail?
The worlds stealthiest airplane would probably be the size of your moms pubes
It would cost about or over 500,000 dollars.
