I inverted colours on whole image (there is also good to add some contrast). I like to have black background and white lines which helps me later with the opacity trick in scene.
Then I cut each view into separate images: top, side and front with ~ coresponding image resolutions and saved them.
I created box in VIZ with matching proportions to the reference images, converted it into the editable mesh and deleted 3 sides. I assigned its own Material ID (1,2,3) to each of the resting sides.
Then I applied multi/Sub-object material on this box. Sub-Material settings are showed on the image below (self ilumination set to full white, speculars off and previously prepared reference images in the opacity slot). This makes visible only the lines of drawed aircraft and they are independent from the scene lighting.

Modeling -
I have downloaded some photos of real aircraft to have some additional reference. It is good for begginers to go through some tutorials and pages about this problematics before start the modeling.
Some links on sites which can help you:
And finaly, I can really recommend to consult your work with more experienced friends and people arround you. For example, when I went to a pub with friends I took some mesh prints of my model and friends showed me where are mistakes or where improve topology.
I have chosen fuselage part under a cockpit as my starting point. Then I continued extruding and adjusting mesh to fit blueprints. I modeled only half of plane and then used mirror modifier. And in the end applied turbosmooth modifier. Some details like pilot tube are made as separate objects. Ailerons/elevators and rudder are made as separate too in case of my intention to animate the jet in future.
