XLII
Just moored the Graf Zeppelin took up almost 800 feet of the runway at Mines Field,
and she would need to make a running start to gain steerageway and altitude in
the difficult climatic conditions of Los Angeles. The towers with their
high-tension wires are not visible in this picture, but along the lower length
of the photo can be seen assembled spectators with their automobiles, all come
for a glimpse of the famous world-conquering airship

On the evening of August 26, 1929, less
than 24 hours after touching down at Mines Field (LAX), Dr. Eckener decided to
lift off and complete the voyage of the Graf
Zeppelin to Lakehurst.
Immediately it was clear that there
were going to be problems leaving Los Angeles. The thermal inversion that the Graf Zeppelin had encountered while
landing had forced the ship to valve a lot of hydrogen lifting gas to land, and
now the ship was heavy.
Usually, the problem with an airship
liftoff was the ship's seeming impatience to be gone. It took a lot of hands to
control a dirigible during liftoff, and ground crews had to be specially
trained to handle the tricky aircraft lest they get away and go floating off
irretrievably.
Men handling the stout hemp mooring lines of airships had been
injured or killed being lifted far above the ground by an errant airship and
then falling helplessly far to the ground.
But not on August 26, 1929. The thermal
inversion was still locked in place, and the hot air above it was making the Graf Zeppelin surprisingly sluggish.
When the mooring lines were paid out, the big zeppelin rose only a few yards
off the ground. There was no way that she was going to rise high enough
vertically to engage the engines and attain steerageway.
The crew tried dumping water ballast
and hundreds of gallons of water, carried all the way from Lake Constance,
Germany, splashed to the ground, drenching the ship's handlers and many of the
thousands of watching spectators, many of whom had been standing around all day
just looking at the Graf Zeppelin.
The ship rose a few more yards into the
sky, but still not enough to engage the engines. The idea was voiced but then
vetoed to wait until morning to lift off. It was decided the sun-heated air
would make leaving in daylight even more difficult.
A frustrated Dr. Eckener ordered the
mooring lines pulled in and the ground crew to stand by. The Graf Zeppelin settled back onto the
earth.
Eckener did some quick figuring,
calculating how many hours the flight to Lakehurst would take, and then he
ordered the ship shorn of extra weight.
The ground crew rapidly unloaded cartons
of champagne, crates of iced lobster and steak and other comestibles, and extra
equipment like chafing dishes and pots and pans --- even shrimp forks. Most of
this stuff was crated up and sent on to Lakehurst by train (but some of it
became instant souvenir material).
Finally, the Graf Zeppelin was made several tons lighter yet, and she rose
unwillingly into the sky above Mines Field. It was still not high enough, but
Dr. Eckener had an idea. He decided that he would make a running takeoff, like
an airplane's. The momentum of the running takeoff would let the ship rise
higher into the sky as it moved.
It was a good idea, but it had two
drawbacks, one merely irritating and one potentially fatal.
It was irritating that the runways at
Mines Field were not built for big airships. They were built for small
aircraft. Airplanes needed far less runway room to gain altitude than did a 776
foot airship. At nearly 800 feet, the Graf
Zeppelin consumed a large fraction of runway length just sitting still.
There was a good possibility that the zeppelin might run out of runway before
it attained sufficient altitude.
The land around Mines Field was still
farmland, and the fact that the ship might coast over farmland after running
out of runway was not so much of a problem.
But what was a problem --- a fatal problem --- a nightmare really --- was
that the Graf Zeppelin couldn't just
coast away. The border of Mines Field was delineated by a series of 150 foot
electrical towers carrying high-tension wires that provided all of Los Angeles'
electricity. The Graf Zeppelin would
have to clear the tops of those towers --- at night, with only the towers' own
flashing red lights as a guide --- or risk tangling with the electrical wires
they carried.
For anyone who remembered the Roma disaster of 1922, when that
smallish hydrogen airship brushed high-tension wires becoming an instant
fireball, the thought of a "heavy" flyover was paralyzing. Not only
would the Graf Zeppelin explode
spectacularly in front of tens of thousands of watchers, but its far greater
hydrogen capacity would make the Roma
explosion look like an errant skyrocket. There was no question in anyone's mind
that everyone aboard would be killed. And Los Angeles would be instantaneously
blacked out.
It was a very calculated risk.
Dr. Eckener ordered everyone to hold
tight to the mooring lines as he redlined the Graf Zeppelin's engines. He wanted no forward momentum. Not yet.
Then the order was given to let go, the
mooring lines were retracted faster than they had ever been, and the big
dirigible surged forward. As it moved, the bow of the ship tilted sharply into
the sky --- 45, then 50, then 60 degrees high. Everyone on board was holding on
to something fixed.
The head of the Graf Zeppelin rose so high in fact that the tail fin, 776 feet to
the rear, dragged a long furrow in the earth.
Spectators watched as the huge fore of
the ship cleared the electrical towers with only yards to spare, but many
people closed their eyes waiting for the seemingly-inevitable explosion to
come. It seemed impossible that the high tension wires wouldn't make contact
with the vessel amidships, or with the engine gondolas.
And then --- amazingly --- the vast
ship seesawed on an invisible fulcrum. The aft of the ship rose rapidly into
the sky, clearing the towers neatly.
"He's going to run her into the
ground!" someone screamed. But he didn't. It looked like an optical
illusion. The hugely teetertottering ship was suddenly on an even keel, safely
away from danger, and sailing serenely off into the night sky as if nothing at
all had happened. Liftoff was recorded at 12:14 A.M. on August 27, 1929.
The crowd on the ground burst into
cheers. It was not likely that anyone on board the Graf Zeppelin heard them. But everyone connected with the liftoff
had just experienced the world's finest airship pilot complete the most daring
lighter-than-air maneuver ever recorded in the annals of flight.
There are no photos of Dr. Eckener’s
daring and dangerous liftoff at Los Angeles, but this photo of the Graf Zeppelin over Lakehurst, New Jersey
at the end of the Worldflight gives just a hint of the attitude of the airship
at Mines Field (LAX)
