F-15 Eagle
If you were wondering what 15hrs around the world would look like you should try getting on an F-15 Eagle. Built by McDonnel Douglas in 1967, the Eagle is designed to be superior to any enemy in the skies. The first one of this model flew in 1972 and came into operational service in 1976.
These planes can fly at speeds faster than sound and have often been thought of as the best plane ever made. There have been reports stating that the Eagle will continue its service in the US even after 2025, and has also been exported to other countries around the world.
