A little bit of help is to understand why aircraft are shaped like they are.
One of the reasons that modern aircraft all look the same is that the requirements are similar.
The wings are positioned to be where the centre of gravity is, so for e.g. if the aircraft has heavy rear engines, the wings will be a long way back on the fus.
High wings are chosen to stop damage from crud on the ground for kites flying off rough airstrips, or, to allow props to not foul the terrain.
Then there is the number and position of engines, the fuselage size and shape, and finally the tailplane shape and position.
I live under an air corridor, and have a constant flow of aircraft across the sky, and all I can see for most is a vague aircraft shape and vapour trails!
