| UW's X5: too boring to show |
| NASA's X5: the original -- X5
"Classic" -- the first trans-sonic, variable-sweep-wing jet
aircraft. (Real narwhal tusk protruding from front air-intake led to aircraft line being discontinued because of importa/export restrictions and lack of Antarctic narwhal extradition treaty.) |
| BMW's X5: another gas-guzzler,
slightly slower, but roomier interior. (This one's photographed on Titan -- note blue haze and Huygens antennae peaking up over cosmic gravel mount in upper-right corner.) |
