747-400 Cruise speed

fixed, thanks for reporting

Wouldn't this apply to the 747-400ER, 747-400D and 747-400M as well?

747-400ER is slightly faster (0.855 Mach compared to 0.85 Mach)

747-400, 747-400D and 747-400M are at 0.85 Mach, which is actually 565 mph if you do the math properly

only the 747-8I and 747-400ER are at 567 mph (not 570 and 544 respectively)

but... it clearly says 567 mph in the boing page

it's a typo. 0.85 Mach is 565 mph, if you do the math

Its the official Boing page, not a youtube comment

1. Seriously, it's Boeing, not Boing. (Twice)

2. It doesn't matter if it's the official Boeing page, they could have made a mistake.

3. Just because you don't know how to do Mach speed calculations doesn't mean I don't know how to.
