Strange Bird or Sometimes a Cigar is Just a Cigar

Maybe an accomplished birdwatcher can identify this strange bird whizzing by at sunset today?

Actually, we see this sight quite frequently in the South Bay. During the day, the Spirit of America Goodyear blimp flies toward the coast. When the sea breeze* kicks in, it returns to its hanger in Carson.

* The land-sea breeze refers to the diurnal coastal cycle. It blows from the land towards the ocean when the land is cooler than the sea. When the land heats up, the 'sea breeze' blows from the sea towards the land. Locals call this our natural air conditioning. Airships (blimps) make use of this daily cycle for their cruises.
