iPhone users are sad and mentally unfocused

Statistical nonsense

Did you not mean:

"46.9% of iPhone users who were interested enough in measuring their (un)happiness to volunteer to download a dubious application and volunteer as guinea pigs"?

Normal people who are iPhone users would not have been interested in participating. This sample population is not representative of iPhone users in general.

Miracle airship tech sustained by DARPA pork trickle

Titanic does not begin to describe it

Have you any idea how little lifting power either hydrogen or helium possesses?

A quick back-of-the-envelope calculation shows that lifting 500 tons will require a volume equivalent to a sphere 2900 feet (over half a mile!) in diameter.

This assumes, of course, that the structure of the airship is massless. I am guessing here, but I suspect that any structure strong enough to keep 500 tons of cargo from dropping through the floor will add a good deal of vehicle weight to the equation, increasing vehicle volume much further.
