Synopsis by Alice Day
The blimp was once looked upon as a luxurious and safe answer to air travel. This global view was changed dramatically with the tragedy of the Hindenburg, and blimps were relegated to the advertising world and occasional duty over sports stadiums. Today, the images of exploding blimps are being dispelled, and there is new interest in these airships, which include cyclocranes and zeppelins. In The Blimp Is Back, Nova takes an in-depth look at what scientists regard as remarkable possiblities. Technology has created innovative changes in the blimp, and future uses could include research over the Amazon and police surveillance.
