First model to be made by me using the "Vehicle Modelling Series" as a reference for Separating out Parts, Blocking and Adding Subdivisions as well as Mirroring.
No modeling sheets used though I am interested in searching for Orthagraphic designs to work of.
Incorrect use of the Plane tool and/or incorrect properties has caused some artifacting; namely the fact you should see Mesas and Buttes in the background on the desert. If you look closer you will notice the two leading edges of the tail fins do not have their subdivision surfaces merged seamlessly with the rest of the fin.
I am not sure how this happened, though I suspect this occured when I deleted those vertics because at the time I had Triangles (so I couldn't insert Edge loops to make the fins appear sharper and more Aerodynamic) and to replace it with a Quad on either side of the fins.
