Currently one of the most advanced stealth bombers in the world, the Northrop Grumman B2 Spirit has been used by the US in its recent conflicts to evade enemy radar and destroy air defenses in advance of the main attacking forces. More info here: http://en.wikipedia.org/wiki/B2_SpiritNote this thing was developed from the model that can be found here (not produced by me): http://sketchup.google.com/3dwarehouse/details?mid=9b58b33d3953ecdc605b692dc0f7565&prevstart=0 Print out the file called "B2" that has the two halves side by side. It should take ~1:45. Glue the halves together using some ABS dissolved in acetone. I also uploaded the uncut file for those who may be interested in playing with or modifying it. Since it was designed to be printed in halves, the full wingspan is 200mm so it would need to be scaled to print whole. You would also need to use support material and I doubt it would come out as nicely as using the halves method, but it's there for those who want it.Printing the two halves and attaching them is by far the recommended method. It's the only way I've done it and the details came out nicely. I'm not sure if printing the model whole is even possible, the file is just there in case people want to experiment.
