Reminds me of a an anecdote about the F-117 Nighthawk which was the first stealth airplane nearly invisible to radar. Apparently the engineers working on it would come into the airplane hangers to find many dead bats as it was also invisible to sonar.

Interestingly enough this made the engineers realize the stealth technology also could work for submarines which led to the IX-529 Sea Shadow stealth ship.

The bats died because the radar absorbent material used on the F-117A was highly toxic.
