First El AL 787-9 "Ashdod" 4X-EDA in full livery
(I was hoping the nacelles were in blue like in the renderings but I had a feeling they would be white )
Very few airlines have the nacelles painted in a color other than white , I think I read somewhere that Boeing recommends only neutrals colors as any ridges in the paint will effect air flow and efficiency .
