Hop in an airplane today, and it will get the thrust it needs to fly through the air either from a propeller or a jet engine. Both methods require moving parts — a propeller spins, and a jet engine has a fan inside. And as such, they are loud. That’s been status quo since Kitty Hawk.

But now aeronautics experts at MIT have flown a radically different type of plane that is thrust through the air using just electricity and the movement of ions, a type of silent drive without moving parts out of science fiction.

The researchers flew the airplane a total of ten times at an indoor track at MIT. It weighs a little over 5 pounds, has a wingspan of about 16 feet, and flew about 230 feet on its longest flight — roughly the twice the wingspan of a Boeing 737 — before smacking into the gym’s wall. Its speed is about 11 mph. The tech powering the plane is called electro-aerodynamic propulsion.

“What we achieved was the first ever sustained flight of an airplane that is propelled by electro-aerodynamic propulsion, and that’s also, by many definitions, the first ever solid-state flight, meaning no moving parts,” Steven Barrett, a professor of…
