I'd love to see that happen, the manual gear extension on some old plane where you have to lift the carpet under the ladies. ;D
But who needs a gear anyway? http://www.youtube.com/watch?hl=en&v=b_EjsgLXdb8&gl=US

You may correct me, Lou, but that blocking wheel (with the too high brake pressure on) isn't lost in case of braking, it just brakes less than a rotating wheel would do.
Static friction (rotating wheel, getting brake force on it but remaining in rotation) is higher than sliding friction (stopping wheel, rubber sliding across the runway), so the techs try to achieve a rolling wheel in all cases, which also has the advantage of offering directional stability.
Regarding friction, I've just read about the A380 in Paris, scratching some buildings again. Seems like the folding wings thingy is about to come soon. ;D
What drives those pilots to smash either CRJs or buildings?
But all big things had smaller problems, didn't they?
