I never knew and got curious and looked it up. I guess it makes more sense than slamming your testicals against the wall.

    You can also increase speed by not using any propellers or moving parts. At supersonic speeds you capture the air, compress it into a chamber than hit it with a spark and blow the fucker up. That’s how a ramjet engine works. China just made one that uses pulse like combustions in a engine that’s only about a foot wide, and maybe 13 feet long. Speeds up to mach 4… or 5000km/h (3100mph) at about 65,000 feet.
