University of Michigan Aeronautical Engineers Study Birds

Interesting story from the U of M about aeronautical engineers who study "low Reynolds number aircraft" (i.e., birds). Factoids from the press release:
A Blackbird jet flying nearly 2,000 miles per hour covers 32 body lengths per second. But a common pigeon flying at 50 miles per hour covers 75.
The roll rate of the aerobatic A-4 Skyhawk plane is about 720 degrees per second. The roll rate of a barn swallow exceeds 5,000 degrees per second.
Check out the slide show link in the article. Great photos.
