President Joe Biden has caused confusion after predicting some commercial airplanes could fly at speeds of up to 21,000 miles per hour in the next 10 years, faster than the hypersonic weapons under development by the military.
“We’re going to talk about commercial aircraft flying at subsonic speeds, supersonic speeds, be able to figuratively, if you may, if we decide to do it, be able to traverse the world in an hour, travel at 21,000 miles an hour," Biden said.
The White House has yet to clarify Biden's comments, made during a Wednesday address aimed at promoting his $2.25 trillion infrastructure and jobs spending package.
The speed of 21,000 miles an hour roughly equates to Mach 28, or 28 times the speed of sound.
In comparison, the new AGM-183 Air-launched Rapid Response Weapon, which failed to detach from a B-52H Stratofortress bomber during a U.S. Air Force test launch this week in California, is designed to reach up to Mach 5. The Army and Navy are developing similar ground- and sea-launched hypersonic weapons.
The fastest commercial airplane flies at less than Mach 1.
Some companies, such as Boeing, have been working since 2018 on aircraft that could travel up to Mach 5. Those airliners may not be realized until “before the end of the decade," at least according to rival Aerion, which is exploring its own options.
During his speech Wednesday, Biden pitched his "American Jobs Plan" as a proposal that could help the nation "build for tomorrow."

Why not say we’ll use speed of light rockets to travel to other galaxies by 2028? It would make almost as much sense.
Orbital velocity is 17,000 miles per hour so they won’t be planes for long.
Well, in fairness, how could they?
And they said GWB was stupid.
Will they be all electric aircraft?
C’mon, man!
Joe knows how to science!
I would love to see the wings on those jets.
You’ll be able to find them on the ground far behind the crash site.
Does he even check the stuff he says before he says it?
He’s not adept at extemporaneous speaking.
And can you imagine what the media would say if Trump said that?
He can travel to all 57 states in just one day!
GW flew its. And they still called him stupid.
So planes could circle the earth in a little more than an hour? Biden is nuts/demented.
Look, we’re dealing with a genius here. Biden can take out a sharpie and a napkin at a restaurant and do some quick theoretical physics charts that can take some PhDs three hours to figure out, shaking their heads. “He’s right.”
On batteries?
Not a chance.
Flying that fast is racist - just like everything else.
An hour later you've gone most of the way around the Earth.
You land, and after waiting another hour you've got a couple hours to get to your destination. Total time, let's say 8 hours.
Big damn deal about the fast plane ride, who cares?
Tell me you're going to make it so that I can get from home to being in the air in 2 hours, and that getting off the plane and to my destination takes an hour, and I'll happily take that 5-hour flight.
My God, our President is a lunatic. A freakin' raving lunatic.
“He meant kilometers per hour. Or meters. I’ll circle back on that.”
Considering that orbital velocity is 17,500 MPH, and escape velocity is 25,500, we’re basically talking a rocket.
I remember talk of a hypersonic transport during the Reagan administration. But it wasn’t THAT fast.
Once again, Ol’ Joe was talking out his ass.
No worries, mate. Biden will sign an Executive Order that raises orbital escape velocity to 25,000 miles per hour. Easy peasy!

Solar panels and windmills?
