The USS Liberty incident continues to provide grist for all kinds of conspiracy theories (here and here among others). Recently, the Israeli Air Force allowed a reporter from the Jerusalem Post to listen to tapes of the radio transmissions before, during and immediately after the June 8, 1967 attack on the US intelligence-gathering vessel. One of the pilots involved, Brig.-Gen. (ret.) Yiftach Spector, agreed to be identified for an interview as well.
On that fateful day, a mysterious ship was reported off the coast of El-Arish; the IDF thought the ship might have been responsible for the shelling of an arms depot on the beach. Three torpedo boats were dispatched but then the Air Force was requested to intercept the ship.
