Boeing planes had uraniun

I heard on ALEX JONES at http://WWW.INFOWARS.COM that the Boeing planes have depleted uranium in them and the dust may have poisoned more.

"DU counterweights have been used in commercial aircraft on rudders, outboard ailerons (wing assembly), and outboard elevators (tail assembly). Counterweights come in a variety of weights and shapes, and numerous weights and shapes are used in some aircraft.

The DU counterweight can range in weight from 0.23 to 77 kg." "DU counterweights have been used primarily on wide-body aircraft. However, during the past decade, tungsten has been used to replace DU as the counterweight material." [NUREG-1717]

Use of DU Counterweights in U.S. Domestic Aircraft Aircraft

Type Manufacturer Aircraft Number Owned by Domestic Carriers (a)
DC-10 McDonnell-Douglas 168 (b)
L-1011 Lockheed 60 (b)
B-747 Boeing 202 (c)

Total Weight of Counterweights per Aircraft (kg)
DC - 10 approx. 1000
L-1011 approx. 680
B-747 approx. 850

(a) Number of aircraft owned by domestic carriers that are members of the Air Transport Association (ATA, 1999).
(b) Phone call, E. Lanchester, Quality Assurance Department, Nuclear Metals, Inc., Concord, MA, August 1996.

"In many cases, tungsten alloy counterweights have replaced DU counterweights in aircraft. Since 1981, The Boeing Company has provided customers with tungsten replacement counterweights, and tungsten counterweights have been installed in new Boeing 747 aircraft. Tungsten equivalents have been sent as spares since 1981 (Gallacher, 1994). In 1988, McDonnell-Douglas discontinued using DU counterweights and began using tungsten. Tungsten counterweights are used on the MD-11, MD-80, and MD-90 (Ford, 1994).

It is unknown how many DU counterweights are currently installed in aircraft. It is estimated that approximately 15,000 weights may be associated with the Boeing 747 fleet (based on 550, Boeing 747 aircraft produced between 1968 and 1981 and spare parts) (Gallagher, 1994). However, the number of aircraft that contain DU counterweights is decreasing. Rather than refurbishing the DU (during maintenance operations), tungsten counterweights are used as a replacement."
