** As I understand it, Henry was pro-Adolph in the late 1930s because
both of 'em passionately hated Jewish bankers as well as lox. However,
when Henry saw the mountain of money he could effortlessly make building
B-24 bombers for the war effort, he had a change in heart, and he set up
the famous mile-long B-24 Rouge River production line that was cranking
out a plane every 25-minutes. When the smoke cleared, the B-24 was The
most produced airplane during the war. If all 16,000 or so had been
lined up wing-tip to wing-tip, the shadow would have been c. 1.5Mega
feet, or 300-miles, long -- roughly the distance between Santa Barbara
and San Francisco.

** Money is way more important than humans. Ken Lay's Enron Corp. was a
recent example. American drug companies are a steller example. For
them, a 3000% profit is the American way, and, as old-folks know, a damn
good way to be able to afford to buy Congress.

** Hydrogen gas is lighter than air, so if there a leak, it's outta
there.
Gasoline and especially propane vapours are way more dangerous because
they settle on the floor and can blow one plumb out the garage door.
