On August 12, 1944, Lieutenant Joseph P. Kennedy, Jr., heir to one of America's most glamorous fortunes, son of the disgraced former ambassador to Great Britain, and big brother to freshly minted PT-109 hero JFK, hoisted himself up into a highly modified B-24 Liberator bomber. The munitions he was carrying that day were fifty percent more powerful than TNT.Kennedy's mission was part of Operation Aphrodite/Project Anvil, a desperate American effort to rescue London from a rain of German V-1 and V-2 missiles.
