Speedbird lives up to the name.
Speedbird 112 was the fastest subsonic plane to take advantage of the super duper jetstream this weekend for the NY to London route. Top groundspeed for the 747 reached 720kts. They broke the record by 17 minutes and took 4:56 to do the trip.

Re: Speedbird lives up to the name.
Amazing reading about this on Twitter...lots of people don't seem to grasp the simple concept of airspeed vs groundspeed. "Wow, I didn't know that a 747 could go at the speed of sound!"
Say, what's that mountain goat doing up here in the mist?

Re: Speedbird lives up to the name.
Doesn't the 747 have a fairly high cruise speed anyway? Is there any airliner designed to go near, or over M0.9 in regular service?
Re: Speedbird lives up to the name.
They don’t call it the queen of the skies for nothing. Even the classic 747 bombed around at .88 or so,passing everything around it. Too bad that efficiency trumps speed nowadays . Really wish that Boeing had gone forward with the sonic cruiser design. Time for a truly innovative airliner along the lines of the citation X, .9+ at FL five zero zero.goingnowherefast wrote: ↑Sun Feb 16, 2020 1:43 pm Doesn't the 747 have a fairly high cruise speed anyway?
