Rather cool, to be out in the backyard this evening, and hear a large,
powerful airplane. Look up to see a B-24 flying around. Later a B-17
giving rides. They are at the Livermore Airport for the weekend.

To many ears, including mine, there is no sound in the world to match the
rumble of multiple large radials coupled to 12 - 16 ft propellers. It stirs
the soul.
