Louisiana Jazz, 09/14/65: Relief efforts in Louisiana following Hurricane Betsy. Pilots deliver emergency supplies, while aid workers provide shelter and food to those who were displaced. Betsy made landfall on September 10, 1965, with an intensity equivalent to a Category 4 hurricane. The storm caused a surge into Lake Pontchartrain, breaching the levees in New Orleans and flooding several neighborhoods. Accruing roughly $1.42 billion in damages, Betsy was the costliest Atlantic hurricane until Hurricane Camille in 1969.
