Can We Blame the Mafia on Lemons?

Organized crime consists of highly centralized enterprises run by criminals who intend to engage in illegal activity, most commonly for money and profit. Some criminal organizations, such as terrorist groups, are politically motivated. Sometimes criminal organizations force people to do business with them, such as when a gang extorts money from shopkeepers for so-called "protection".

And while citrus hardly seems like a black market commodity, plenty of blood was spilled in Silicy over it.

This week, a look at how lemons may have lead to the Mafia.

TTFN, Fred.

Why Phoenix's Airplanes Can't Take Off in Extreme Heat

We take for it granted that we can fly from one side of the world to the other in a matter of hours, but a century ago this amazing ability to race through the air had only just been discovered. What would the pioneers of powered flight make of an age in which something like 100,000 planes take to the sky each day in the United States alone? 

Weather can keep planes on the ground. Snow, wind, extreme rain, these make sense. Who wouldn't prefer to fly in nice weather? But can it be too nice? Yes, if it is hot, "...like Africa hot. Tarzan couldn't take this kind of hot."

This week, a look at why airplanes can't take off in extreme heat.

TTFN, Fred.
