Subject: Re: Air Crash near Pattna? India
It wasn't a Boeing 747 which crashed near Patna, India. The BBC, Times of India and the Hindustan Times speak about a Boeing 737-200.
The Hindustan Times <http://www.hindustantimes.com/nonfram/180700/detfro01.htm> mentions in a report of today that the plane was 20 years old. A spokesman from the Civil Aviation secretary tells that the accepted life-span was 15 years.
In a 17 March 1999 letter to Laka, Boeing's Director Air Safety Investigation Ronald J. Hinderberger denies the use of DU in any other planes than the 747 and the DC-10. In the last paragraph of this letter he says:
"You mention "stories" from people who say that DU was used for "positioning of the center of gravity" or for balancing the plane after being loaded with cargo. While it's true that some airplanes use ballast for center-of-gravity control -- some Boeing 727 and 737 airplanes, for example -- Boeing has never used DU as the ballast material in those applications."
An interesting remark. The "stories" come from an former insider, who is absolutely sure about the use of DU in the other Boeings, but don't want to speak publicly because otherwise he's afraid to losse his current job.
