During World War II, new technology was developed to take out German strongholds in Nazi-occupied France. Called Operation Aphrodite, this mission involved remote-controlled Boeing B-17s, loaded with explosives, flown into the Nazi bunkers at Mimoyecques. It was from these bunkers that the the Nazis fired V-3 cannons into London, destroying so many homes and factories.
Persistent allied bombing rendered the large-caliber propellant guns useless, but many planes as well as pilots were lost, including Joseph P. Kennedy Jr. — the elder brother of John F. Kennedy.
Now, pilots belonging to the global group — the 9/11 Pilot Whistleblowers — have charged that many of the same concepts behind Operation Aphrodite were later applied to 9/11. In short, the whistleblowers allege there were no planes commandeered by Islamic terrorists, but simply planes loaded with explosives flown by remote control — an uninterruptible autopilot system — into specified targets. Two of those planes hit the Twin Towers in New York City, while the third plane hit the Pentagon.
