There was a program on public television just before the 777 went into service; on it there two comparisons with the 737. First that the engine nacelles on the 777 were about the same diameter as the 737 fuselage; second, the horizontal stabilizer span (that's the tail wing for all those knowledgeable journalists out there in La La Land
) on the 777 is the same as the wing span on the 737. Sorry for the sarcasm, the devil made me do it!!
