This confusion arises because aerostat has two different meanings. There is some confusion around the term aerostat with regard to airships. Airships are still used today in certain niche applications, such as advertising, freight transportation, tourism, camera platforms for sporting events, geological surveys, aerial observation and interdiction platforms, where the ability to hover in one place for an extended period outweighs the need for speed and maneuverability.

Their decline continued with a series of high-profile accidents, including the 1937 burning of the hydrogen-filled Hindenburg, and the destruction of the USS Akron. Rigid airships are often called Zeppelins, as the type was invented by Count Zeppelin and the vast majority of rigid airships built were manufactured by the firm he founded.Īirships were the first aircraft to enable controlled, powered flight, and were widely used before the 1940s, but their use decreased over time as their capabilities were surpassed by those of aeroplanes. The framework contains numerous balloons, known as "gas cells" or "gasbags" which supply the static lift without having to bear any structural loading. Rigid airships have a structural framework which maintain the shape and carries all loads such as from gondolas, engines. Semi-rigid airships maintain the envelope shape by internal pressure, but have some form of internal support such as a fixed keel to which control and engine gondolas and stabilizers and steering surfaces are mounted.
Blimps are "pressure" airships where internal pressure, maintained by forcing air into an internal ballonet, is used to both maintain the shape of the airship and its structural integrity. The main types of airship are non-rigid (or blimps), semi-rigid and rigid. All modern airships, since the 1960s, use helium. This meant that this non-flammable gas was rarely used for airships outside of the USA. Helium was rare in most parts of the world, but large amounts were discovered in the USA. The first lifting gas used was hydrogen, although this had well-known concerns over its flammability. Unlike aerodynamic aircraft such as fixed-wing aircraft and helicopters, which produce lift by moving a wing through the air, aerostatic aircraft stay aloft by having a large "envelope" filled with a gas which is less dense than the surrounding atmosphere. After lunch, and in the A's fashion, everyone went on their merry way home.Dirigible airships compared with related aerostats, from a turn of the 20th century encyclopediaĪn airship or dirigible is a type of aerostat or lighter-than-air aircraft that can be steered and propelled through the air using rudders and propellers or other thrust mechanisms. They allowed us to park on the grass and it was great to see all those A's and old time cars parked side by side. Īfter our tour, we enjoyed lunch at the Hanger Four Grill.

Hanger One is one of the world's the largest free standing structure covering 8 acres. His Medal of Honor is on display at the museum.
In December 1915, Moffett received the Medal of Honor for his captaincy of the USS Chester in a daring and dangerous night landing in 1914 at Veracruz, Mexico. Moffett Field's namesake is Rear Admiral William Moffett, who lost his life in the crash of the Macon’s sister ship, the dirigible Akron. The Moffett Field Historical Society is dedicated to education about and preservation of the heritage of one of Northern California’s most significant historic sites-Moffett Field. Len Flaherty in his '56 Pontiac, Steve Graffe in his '36 International Pickup, Miles Hampton in his BMW, Dean, Lorrane, and Mitch Johnsons in their '69 Mustang Coupe, Maureen and Ed Krantz in a '70 Opel convertible, Bob Moll and Ed Wong in a '87 Chrysler convertible and Ted Panofsky and granddaughter, Clara in their '36 Dodge Pickup We were also joined by the Mid-Peninsula Old Time Auto Club: Lowell and Jessica Wolfe, Sam and Connie Asaro with guest Rose Kaufman, Bob Czinder, Bill Kerns, Rick Kessler, Bob and Jane Reed with guest Jack Fisher, Mike Anderson, Vince and Marilyn Perry, Neil and June Chichizola, Barbara Stouffer, Bill and Elizabeth Mitchell, Bob Perkins, Maureen Morley and of course Mike Chapman, tour organizer and Janis. The following El Camino A's were there to enjoy the fun: In the A's fashion, he lead us around Wellesley Park twice before beginning our trip down El Camino Real. Lowell volunteered to lead us on our convoy to Moffett Field.
The El Camino A's met at Wellesley Crescent Park at 9am. There were 10 A's and 7 old time automobiles with a total of 36 people What a great turn out for the Moffett Field Historical Society Museum Tour and Lunch.
