Depleted Uranium used as ballast in 747
Is it true?
A National Geographic docymentary tried to light up a 747 Corean cargo plane that crashed just outside Stansted airport a few minutes after take off.
The reason I am reporting this is that NTSB restricted the area not for the usual reasons only but additionally to another one.
That reason had to do with the depleted uranium used to rudder and wings as ballast.
Even though there was no leakage then I have to ask ...
Why do they use depleted uranium in public transportation? What is the purpose?
Is it safe from the point of radioactivity even though it is depleted uranium?
What about the safety of the crue which fly the planes around the clock?
