Aw, you guys are nuts! The wing span has to be wide enough to create an air foil to catch the air and then you gotta have speed. Not the drug type but air speed. Then if the runway is too short to the thing will never get off the ground anyway regardless of wing span or air speed. well if the air speed is fast enough it may get off the ground but then you have to have a pilot who is brave enough to meet the challenge of a Sonic limeade before he crawls into the box office (can't say cockpit with the PC crowd). So most bears live int he woods anyhow along with the elephants. I'm having a good night, sometime I'll tell you how I was born into a poor Black family and there was only one bed.... I think I'm the one that needs professional help, there are institutions for folks like me.
