We wrap up Airship week with this picture of the Hindenburg. Yes, while we all enjoyed the pictures of elegant travel via Zeppelins, it all came to an end with the Hindenburg. The "lifting" gas used in the old Zeppelins was Hydrogen. There were two reasons for this. Hydrogen gas is the lightest, so gives the most lift when used in an airship, and secondly Germany did not have ready access to large amounts of Helium, which would have been the second best choice of a gas. The thing about hydrogen is that it is very flammable, and it is always prone to leaking. So, Zeppelins were in fact disasters waiting to happen. We share the famous news clip of the Hindenburg disaster below.
