I also wanna add these prototype beauties to the collection:
Knotty and I had the privilege of seeing the very first F-18 at the wonderful Air Museum at China Lake Naval Aviation Test Base in California several years ago, and the colour scheme made a real impression on me, (probably helped by how immaculate she and every other aircraft in the fine collection was kept).
And the F-20 has to take out the honour of one of the most striking colour schemes ever carried by a prototype.
