These are machines. Machines break, no matter what the maintenance regime is. The number of cycles on these planes is awe inspiring, and while there are always squawks, the captain and FO always have the authority to ground a plane for any maintenance items they don't like.

Exactly the same thing would have happened. Maybe if it was raining or very cold we wouldn't have quite as much passenger cell phone footage from the runway. But weather had nothing to do with this, nice weather didn't make the landing any easier, and bad weather wouldn't have made it any harder. Ridiculous.
