Side A: Wind increasing in volume. Get no chance to . . These were the last words from the doomed Navy airship Shenandoah, caught in a violent storm and crashing 7 miles southwest of this spot near Ava at dawn, September 3, 1925.

Smaller blimps replaced the dirigible as America’s lighter-than-air sentinels of the sky.
