Yeah especially the guy that has to remove the support and run like hell. :woohoo:

I like the guy with the cutting jaws. He gets the fun job of reducing everything left over to shreds. And he is damn good at it too

I guess most people missed the part about removing the depleted uranium?

Meh i get to demolish houses every day, just as fun. :woohoo:

Depleted Uranium (DU) was only used in the first 550 747s made, after that they changed to different type. It was only used as counter weight for the elevators. This one unfortunately was one of the first 550 made

It was only used as counter weight for the elevators.
I studied this some years back and it was used in the engine nacelles. The "podded engine" (hung under the wing Vs burying them inside the wing - Comet style) required more weight at the intake to keep the CG sensible.

Didn't know about engine nacelles. I only heard about the counterweight balancers in the tail fin / elevator area

Having DU in engine nacelles would only make sense to reinforce the nacelles and engine housing to protect it from uncontained engine / turbine failures

WTF are you two talking about...

Depleted Uranium is very dense, heavy and strong metal. Strong to the point that it can be used as armour plating. It also happens to be highly radio active. In this case as shown in the movie above it is heavy but it also takes up little space. And in aviation where space is limited it is used to ballance out centre of gravity of the aircraft. It can also be used in the engine covers as armour plating to contain possible engine failure. Uncontained engine failure in a jet engine can be highly dertructive. Imagine the the engine spinning at few thousand revs per seccond. if something was going to let go, all the parts would more then likely exit the engine casings and risk punching the wing or fuselage surfaces, thus causing the aircraft to loose control in flight.

Here is a video of a controlled engine failure test

In real life the perfect example was the Qantas Airbus A380 over Singapore year or two ago.
