You're going to see us traveling commercially in the next 20 years at 12-to-15 thousand MPH subsonic speeds

You won't see anyone traveling commercially at those speeds in the next 20 years. A commercial jet cruises at around 550 mph.

And 12-15 thousand MPH isn't "subsonic". At all. Other than getting those basic facts completely wrong, nothing wrong with what Biden had to say.

God, this nation is in so much trouble. The POTUS is senile.

And therefor Dangerous and a security risk.

The legendary British-French Concorde, had a much longer life-span as a commercial passenger plane. Entering service in January 1976, it had a top speed of Mach 2.04 (2,180 km/h or 1,534 MPH) at cruise altitude. It exited in 2003, having had one fatal accident three years prior when Air France flight 4590 crashed just after taking off from Paris-Charles de Gaulle.

The 747 is one of the largest commercial aircraft ever built, and the 747-8 Intercontinental (747-8i) variant wins the race as the fastest commercial plane in service today. This plane is as tall as a six-story building with a top speed of Mach 0.86. That's equivalent to 659.85 mph.

Sure Biden read his teleprompter wrong. We don't have the aeronautics and metallurgy to travel 12 to 15 thousand miles an hour now or in 20 years.

Imagine, according to Biden, you can go around the earth in 90 minutes. That is as fast as the ISS moves around the Earth and that is without air resistance. Beam me up Scottie.

In 20 years, you will be lucky to travel at 60mph.
Then you will have to recharge for 8hrs.
