It never ceases to amaze me how incredible a piece of machinery the 747, or really most any commercial airliner, is. There is a quote that Mark Shuttleworth cites on his blog:

"When once you have tasted flight, you will forever walk the earth with your eyes turned skyward, for there you have been and there you will always long to return." — Leonardo da Vinci.

And I believe this to be true to a certain degree. Every time I see a plane in the sky I take a little time out to admire it. Anyway, this is a very good submission. Thanks for sharing!

Unfortunately I can't link it of course, but it's even more amazing when you have access to the CAD data that goes into one of these.

Can't go into too much detail, but we do aerospace/defense work, and these things are marvels of engineering.

Doing Seadragon-style navigation through the entire aircraft is amazing.

Hope that doesn't give away who I work for, or I may be in trouble, since this stuff is still under wraps, no-one else does navigating 120GB models well...yet ;)
