1. The alternative liveries:
Normally there is 1 or 2 or max 3 of them. 3 is very special, and not to mention 6. So I thought, if I put the other liveries to the same size as the original, it will look good next to it, if there is only 1 or 2 special repaints. I know 6 big ones may look ugly together, but I thought about the normal 1 or 2.
2. The first four sentences:
Well I had a concept in my mind, how would I select a plane for a flight. It is me only, I do not know how others do it

. So, the first point is the sympathy about an aircraft, than the technical specs. But what specs do I need to now, when select the plane? I thought that these four are the most important ones to know...ok, maybe the engine is not. Then I select a perfect plane I can bother with the other information more detailed.
3. I may paint a beautiful stewardess in a EuroHarmony uniform. You can vote here for the desired model

Claudia, Naomi, Cindy, Adriana... We could introduce her on the Passengers Info page

4. I did not take the point on the documentation issue. If you thought about script documentation, then I did not planned to document it...there is only 1 very small and in-built javascript in that page, no PHP.
