We have written before that Second Life has the best selection of 3d plane MMORPG options out there. The below high definition video contains one of the most realistic 3d re-creations of a Boeing 737 that I have ever seen in Second Life or anywhere. From the spinning engines, to the flaps on the wings, to the safety lights on the rear of the plane. This has many practical and fun uses in the virtual world.
Although the short takeoff distance was a little unrealistic, maybe that is something that Boeing can shoot for in the future. Check out the three and a half minute long video below.
