★ Martin B-26 Marauder ★ The B-26 was a medium bomber that could deliver 4,000 pounds of bombs on a target 1,000 miles from its home base. Built by the Glenn L. Martin Company near Baltimore, Maryland, the bomber got the nickname “Martin Murderer" because of the high number of landing accidents.  Its fast approach speeds were a challenge for inexperienced pilots.  By the end of the war, it held a different title: “most survivable.” It had the lowest loss rate of any Allied bomber. The B-26 being restored at the National Air and Space Museum flew more missions in Europe than any other U.S. aircraft: 207.
