After Mitt Romney joked that "the windows don't open" on Ann Romney's plane, which filled with smoke last Friday, Russian Deputy Prime Minister Dmitri Rogozin offered to send her a replacement: the AN-2, an old Soviet biplane which had a notoriously dubious safety record.

"No problem! We'll send our AN-2 to Romney's campaign headquarters," Rogozin wrote on Facebook last night.

"Not only do the windows not close, but the doors sometimes swing open mid-flight. On the plus side, there's fresh air to breathe, and you can take in the nature," he added.
