Who was this lucky man who escaped death in the air twice, once by a full bladder and the second time through sheer luck and the skill of his pilot? His name was Lyndon B. Johnson, and he would later be elected president of the United States.

 Lyndon B. Johnson, the 36th President of the United States, did have a notable experience during World War II that involved a plane incident. In June 1942, during a wartime mission in the South Pacific, the plane he was on had mechanical difficulties. While flying over the dangerous Solomon Islands, the aircraft's engine malfunctioned. In this perilous situation, it is said that Johnson exhibited calmness and skill, guiding the plane back to safety.

However, there's no widely recognized account of him escaping death twice, once due to a full bladder and another through sheer luck and pilot skill. It's crucial to note that historical narratives can sometimes be subject to exaggeration or confusion.

Lyndon B. Johnson's political career was indeed remarkable, spanning from his time as a congressman to the Vice Presidency and eventually the Presidency after the assassination of President John F. Kennedy. His presidency, from 1963 to 1969, was marked by significant domestic reforms, particularly in the areas of civil rights and social programs.

In summary, while Lyndon B. Johnson did face a life-threatening situation during his military service, the details of escaping death twice, including a scenario involving a full bladder, don't align with widely accepted historical accounts.
