    Quizzical Pursuit - The Architecture Puzzler

    by Dave Guadagni

    Answer for Last Week's Puzzler

    What do you know about lightning? True or False:

    The Empire State Building is struck about seven times a year.

    On average, a commercial airliner is struck once during every 5,000 to 10,000 hours of flying time.

    Roughly 2,000 thunderstorms are in progress over the earth's surface at any given time, producing as many as 100 cloud-to-ground discharges every second.

    The Midwest states experience the most lightning activity in the United States.

    A lightning channel is about 8 inches (20 centimeters) in diameter.

    A lightning flash could light a 100 watt bulb for 3 months.
