Re: Fire escape tubes etc. New York Times needs helps in physics.

The Science section of The New York Times (October 9, 2001,
page F4) has an article about innovative approaches to fire
escape systems. They say that 25 traffic control towers at the
Air Force bases (not very high structures) already have escape
tubes slung from roofs and windows. People (up to 24 at the
same time) can slide down for safety, they say. Designed for
up to 15 stories they can be used to slide down to the roofs of
nearby buildings. Parachutes, cables and flying platform
approaches are also described in this article.

I've lost some faith in NYT in the past day.

from an article I picked up at a Physics conference (formatted as a small
news paper - apparently targeted for teachers to distribute to classes).

New York Times

2001 Issue 1

Article: High-Tech Jump Suits Help Pilots Avoid Gravity's Perils.

-it gets worse-


Side bar in article:

"What are G Forces:
When manuvering the plane, fighter pilots are subjected to powerful
centrifugal forces that create far more pressure than gravity ordinarily
exerts on the body. The force of gravity experienced on the ground is 1G so
pressure equal to four times the weight of gravity is 4G's."

Picture shows a pilot seated with a down arrow labeled blood flow, and up
arrow labeled anti-G pressure.

Article itself was not nearly so bad.
