Silly Question,Right?
I just wanted to ask. Why? well, I too think I have the answer. They are or can be a lot of fun to build. And the Markings ( or Livery if you prefer) can run the gamut. Some Birds are very colorful , some kinda plain. Now my interest runs from the very early years, think (Tri-Motors here), but, not Jets.The sheer number of planes that you could build would actually stagger the Imagination.
Now remember you have various iterations from Various countries, Some similar, Some Unique. All the way to the Jet Age! I was at Lake Washington when the 707 with Boeing Livery did it's Barrel Rolls over the crowds, Even the Boat nuts looked up at that! Imagine, D.C.7Cs and 8Bs as well as the twin engined short Hop D.C.6 planes that populated our airports. Everything from Full Fledged Airliners to what some call Puddle Jumpers like the Beech Super 18.
The markings? Well, there were airlines that had names that I wondered who came up with them! Everything from Capitol(Regional) to Joes Sight-Seeing Service in a twenty year old Beech! Ah! those were the days. The wonderful Smells, The burnt oil smoke from those babies as they fired up, The Vibrations as they revved at pre take - off spots , then the Rumble and Roar and Vibrations again till the smooth translation to Cruise Power for the flight! Not so today, But boy, they're still Pretty!
