The Beluga is a beauty compared to the Super Guppy it replaced.
As for those comments on the British aircraft being ugly, I mention the Shorts Seamew pushing me to call an aircraft ugly on the first page.
Anybody that can look at a Hawker Hunter, EE Canberra, Supermarine Swift, Hawk trainers, any of the DeHavilland twin boom fighters, any of the V-Bombers or the TSR.2 and not see things of beauty should be making a trip to the optometrist.
Lets not forget, America gave us such "darlings" as the B-52, F-4 Phantom II and what I would consider to be two of the least aesthetically pleasing postwar jets to ever see regular service, The A-10 Warthog and the F-105 Thunderchief. (Note, I didn't ever say "ugly") :-)
