A remarkable pic of the Jet Blue nose gear...

Airbus may not know how to make a landing gear mechanism that works
reliably, but they sure do know how to make it TOUGH. It's hard to
imagine the stresses on that gear as the wheels ground themselves into
oblivion...

I don't know for sure, but it may well be that this caused less stress
than the tires would at maximum braking. I'm guessing the wheels are
aluminum and once it got hot and began to melt, the friction may not
have been all that great.

If you don't believe me, make a skid that has an aluminum plate on the
bottom and make another and put cut up tire treads on it. Place a
hundred pounds or so on top and then try to slide each across your driveway.

NIce clear pic! I see that the tire is still on the right side rim.

I think the one that landed here in Columbus a few years ago, the nosegear
straightened itself out on touchdown, no damage.

That is amazing, ground down to the axle.

Sure is amazing. Also amazing that they didn't design a failure mode
that leaves the tires aligned and locked in the aligned position when
failed.

....after the tremendous force spike of the side loaded rubber tires.

They have to be tough to survive my landings! Not to mention the tug drivers
at LaGuardia! Plus those JetBlue Airbusses are getting old. They're 6 years
old already! :-)

Last year, a Fed-Ex A-300 widebody landed at FLLwith the main wheels locked
up. It stopped in 2700'. All 8 wheels were ground down to the axle. Then a
DC-3 blew a tire and shut down the other wide runway. What a day!

What does the flight manual say about cool down time after that kind of
braking effort?

Good thing the wheels stayed perpendicular to the nose, if the nose wheel
was cocked at 45* or something other than straight or 90* you would have a
wild ride when the nose wheel touched.

Yes, that would have been a real test of pilot skill. I wonder if the
rudder, asymetric reverse thrust AND differential braking could overcome
a 45 degree nosewheel? I'd hate to be part of the crew that had to find
out.

Appeared to take nearly a week. I heard from an inspector that the pilot's
colleagues let loose on the fact that the pilot was female. She in turn let
loose that she had stopped an A-300 in 2700' and no one else in the company,
male or female, could beat her record. Pilots and beer- what a combination!
