Aviation legends Dick Rutan, left, and his brother Burt Rutan, toured the National Museum of the U.S. Air Force on Thursday. Both men visited aircraft that were significant parts of their careers including this F-100F Super Sabre in which Dick Rutan flew mission in Vietnam. Burt Rutan climbed into the XC-124 tiltwing aircraft he helped design in the 1960's, just after completing college. TY GREENLEES / STAFF
