How Do You Stop A Million Pounds Moving At 200mph?

And no, I'm not talking about Rosie O'Donnell chasing a cheesecake truck...I'm talking about a new Boeing 747-8 undergoing stop tests...with deliberately-manufactured bad brakes, just to make it interesting.

Boeing 747-8 Ulitmate Rejected Takeoff Video.

They say those brakes reached 2,500 degrees, and you can actually see them glowing once the aircraft is stopped. Way cool.


  1. Hey Murphy,

    As an aircraft mechanic I inwardly cringed but was still impressed by the sheer stopping power shown. Way cool video:)

  2. I would think the smoke coming from those brakes would scare the poop out of the passengers (or, at least, out of me). I'd expect to see people going down the slides after that if the airplane was actually full.
    Impressive, though.

  3. Two of my friends worked on the flight test program for that model.

    They've got some pretty interesting stories.....

  4. Somehow, "2500 degrees" and "way cool" seem incongruous in the same sentence. Just sayin'

  5. Oh, So all that smoke wasn't supposed to be there when we were flying and you landed your 172 like that, right?

    1. Hey, if you want to get down and stopped in 30 feet, you need to use a little brake.

  6. That's extreme testing. Amazing equipment.

    The brakes got just a little warm.:-)

  8. We routinely took off at 800,000 pounds(E4B). We had a pilot that was a real good 'stick', unless he was landing. His last name was Silver, and he was nicknamed 'HiHo Silver' because he always bounced that sucker on landings!
