Saw it - amazing. Stopping something that heavy in just a few thousand feet!!
 
Very cool test. Brakes glowing red hot. I wasn't sure if I saw a few licks of flame or if that was just the glow from the discs.

Wonder what the A380 equivalent looked like?

I wonder if this test included the extra 30 tons or so of passenger and luggage weight?

I guess I had the sound turned off. Thanks.

I notice the tires are flat after the test. Someone told me that the pilot can deflate the tires. Is that just done to lower the plane in a controlled manner to the tarmac rather than letting the brake heat cause a blowout and subsequent rapid drop?
 
Those tires and/or wheels generally incorporate a thermal fuse that blows out or melts when things get a bit too warm....

Pretty sure the tire deflation was explained in the commentary, I think 49again is correct from what I remember.
