Why are airships safer than today they were in the past?
Modern airships use Helium for lift which is non-combustible whereas in the past airships such as the Hindenburg used Hydrogen for lift which is highly combustible. In addition, modern airships take advantage of new alloys and polymers which give them a much stronger airframe.

Actually, they aren't that much different. We think that the earlier time was safer and that people were happier, but this is all perception. It was no safer or less safer than we are today. In some respects we have things that make it safer than the 1950's. A cell phone is one thing that makes it safer. Instead of having to look for a phone booth we carry the phone with us. Cars are safer. In the 1950's there were no seat belts and air bags in cars. Airlines are safer because of the new methods of air traffic control and computers. These are just a few things that make it safer today.
