Among Graf Zeppelin's aviation feats was her non-stop
flight around the world in 1929 with 20 passengers!
Graf Zeppelin logged over 1,000,000 miles, carried 18,000
passengers safely from 144 Atlantic crossings using hydrogen as
lifting material.
Airships are far more efficient for transportation than modern
aircraft which carry heavy fuel loads and fly at speed to stay
aloft, yet airship use were shut down in favor of aircraft which
consume ungodly amounts of fuel.
Was the Hindenburg sabotaged so the aircraft and oil industries
can benefit ?
Hydrogen separated from oxygen in a sealed gas cell
(Hindenburg had 16 separate cells) does not burn.
A lit match inside a hydrogen fuel cell would immediately
go out (as soon as the oxygen in the match head powder was
exhausted.)
If a static spark ignited Hindenburg, it would burn on the
outside of the ship's skin like a gas torch where air containing
oxygen mixed with the hydrogen escaping from a leak so how could a
flame burn inside a gas cell devoid of oxygen?
Hindenburg had instruments that detect changes in gas
pressure so any leak would have been detected and the pilots would
stop getting close to any structures and correct the problem.
[This story is similar to TWA's doomed flight 800 reported by the
media that the center fuel tank "exploded". The TWA flight
800 examination commission paid millions to a government contractor
to conduct tests that would show how the fuel exploded within a
similar tank and after trying every possible manner of detonating
jet fuel "fumes," they never could get it to go off and they left
that fact out of the report.]
