This is the Lockheed L-1011, a very amazing plane made during the 70s, and the direct opponent of the dc-10, althought it was a very advance ( probably to much for its time) and good aircraft , it was a commercial failure because of the economic issues of Lockheed and stuff.
Btw, i must admit that this model is not mine, its made by the Sketchup user 707, so consider seeing his work on Sketchup, im no taking credit on it i just want to realease it to the thingiverse.
