Airships had a great advantage over heavier-than-air planes; a quiet flight.
What ever happened to dirigibles, anyway? The word "dirigible" just means "you can steer it" - a big advance on balloons that just floated around. For a long time, the Graf Zeppelin held the record for around-the-world flight (21 days). Yes, the Hindenburg disaster showed the problems of using hydrogen; but helium is a noble gas and won't catch fire. So, what happened to dirigibles?
Well, the United States Government is partly responsible. Helium is common in the universe; about 23% of the detectable mass of the universe is helium. On Earth, however, helium is rare; most of the free helium is in the exosphere, where extracting it is difficult. However, there are natural gas wells in Texas with a relatively high concentration of helium.
In the 1940's, the government became concerned about Germans attacking with non-flammable dirigible war planes. How to stop this threat? Cut off their supply of helium! So the Federal Helium Reserve was established in Amarillo, Texas in a natural underground formation with room for roughly one billion cubic feet of helium.
The Federal Helium Reserve still exists today. And although the threat of foreign lighter-than-air warship attacks never materialized, the debate over what to do with this helium reserve is hotly debated. Once it is gone, it will be very difficult to get more economically. Concerned about helium? Read more here. Comment/Join this discussion ( 2 ) | RSS/XML | Blog This | Additional
