Omg I cried at the end,
Victor X-ray ur cleared for takeoff
Make us proud!!! -
No matter what anyone says, the Boeing 747 was NASAs transport aircraft to get the Shuttle back to Florida if she landed elsewhere. It has also been Air Force One for the American President (there are actually two planes; both go, so if a problem develops, the backup plane is used. They can also be used to confuse any enemy that tries to shoot it, and the President, down. This guy on scene had to have considerable clearance to be that close to the plane while under refurb. Maintenance people are rather possessive about the planes they are responsible for. When being flown by an airline, it is a flying hotel.
IIRC, a "D-Check" costs almost more than its original cost. It is b/c every nut and bolt is removed, inspected, and replaced. The fuselage is tested for cracks at the atomic level by a mass spectrometer, and any apparently worn item found internally is replaced b/c after the aircraft is re-assembled, it can be impossible to replace it..
Many years ago, a much smaller jet turbine was removed by the maintenance crew, and dropped. the drop put a crack into the bracket by which the engine is attached to the bracket used to attach it to the wing. Some time later, the plane was on take-off, and the jet engine broke off from the wing. The plane rose, then the pilot lost control, and then the plane went down, killing all on board. The NTSB examination found the broken bracket, checked the records, and saw that the engine had been dropped. There was much weeping and knashing of teeth.
When torn apart, the melted aluminum is the most prized metal, b/c aluminum ore is very expensive to process; it takes a fortune in electric power to heat it up, purify it, then pour it off into ingot blocks for transport to a raw metal broker.
During the life of any airplane, the mechanics who take pride in their work, will call it "their airplane", and when it is signed over to its crew to fly, they go with it as well. They are along for the ride in spirit, b/c they helped give birth to it. -

The question "why are there dislikes" comes to mind

victor xray is so cool

hello great video earnt a new subscriber

i love this

Totally agree with many of the comments below...this is one of the best Engineering documentaries I've seen in a while.
I don't think they could have found better presenters than Rob and Tom.
(Tom looks nothing like Weird Al, btw). -
SUPER 747
