I'd like to put a few myths to bed. There are some people on here claiming they know how this scheme came about and believe me, they don't. What I'm about to say is based on pure fact alone.
The design was indeed brought to life by one of the youngest members of the ground crew. The entire Sqn had a competition for designs and his came out top. Let's not forget that to people that belong to the Sqn, there are plenty of little details in there that are lost on people outside of that group. The aircraft has been painted to celebrate the centenary of the Sqn and not to win any design awards. I've seen on here that the C being yellow doesn't fit. Well that's there to highlight the roman numeral for 100 etc. Some people say that the colours chosen don't go together. Well again, those colours are an integral part of the Sqn and are steeped in history.
The evolution of the design was difficult and the process to get this approved is a long and complex one. I can say though that no wholesale changes were made to the original design. A few tweeks were made because the approval process insisted on this design being coordinated with the 2 Sqn Tornado. So please don't think that the Sqn had a free hand in being able to do whatever they wanted.
I've seen a few comments about battle honours. They were aiming to put them on the foreplanes so when they were in the parked position anyone looking at the front of the jet could see them. It was the approval process that forced the change to the intake.
On a slightly different note, the Typhoon force is exceptionally busy and let's not forget that Op Ellamy wasn't that long ago, 3 Sqn are only just back from a detachment and the guys and girls of the Armed Forces are committed to supporting the Olympics. So I for one believe they've done a great job, with not a great deal of time and not a great deal of manpower to take on projects like this.
I can also confirm that the Typhoon could, if so desired, be painted in pretty much any colour that was chosen. The reason it isn't, well, let's not forget what the aircraft does. For operational reasons, they remain the grey colour. Technically, the paint scheme as a whole is different from say a more traditional all-metal jet like Tornado, and as such it does take more time and effort to strip a predominantly CFC Typhoon. The GAF chose to use a vinyl wrap for the tail of the 74th FBW at jet at Neuburg by the way.
So in summary, I think they've done a great job and look forward to the next Typhoon paint scheme. Too many people on here love to jump to the negatives without really understanding the full story.
