I would probably try to match the font of text above(I can see an "O), italics/white stroke. I probably would create the text in a precomp and use a cylinder effect to give it a bit of a bulge to match the plane fuselage. Then I would play with the blending modes, overlay and screen usually work well, but the bands of color will probably be cause issues, so maybe multiply. Also I wouldn't use a drop shadow, you never would see that on a plane.
