I took this close-up of the Goodyear Airship ‘Spirit of America‘ during a pass almost directly over the house this past weekend.
You can see the twin 210 horsepower engine nacelles configured as pushers. Behind the props are a pair of scoops which collect some of the propwash to direct airflow to ballonets which assist airship trim and control. The gondola is about 22¾ feet long and can hold a pilot and six passengers.
Coincidentally, the light display had the word ‘ON’ displayed which looks like it’s saying ‘NO’ from this angle.
