Years ago, there was a speedier way to travel, as the Concorde supersonic jet offered flights from New York to Paris in just 3.5 hours.
But that quick jet was retired in 2003, and wasn't as enjoyable as it would seem since it was incredibly noisy.
Now, NASA is working on developing a supersonic airliner that is quiet.
Boeing is also helping, as they have already submitted a few concepts for the airline. One features a design where the engines are on top of the plane, shielding the ground from their loud noise, and a V-shaped tail that funnels the sonic boom backward.
Boeing says by keeping the sonic boom backward, it would stay in the air for longer and away from people on the ground.
NASA is testing these concepts at its Glenn Research Center in Cleveland, Ohio.
"We are testing overall vehicle design and performance options to reduce emissions and noise, and identifying whether the volume of sonic booms can be reduced to a level that leads to a reversal of the current ruling that prohibits commercial supersonic flight over land," they said.
The Concorde traveled at 1,354 mph, or Mach 2.04. That's more than double the cruising speed of jets in use today.
