I don't know who told you that your mom's uncle was a kamikaze pilot during pearl harbor, but they were mistaken. The first Kamikaze attacks weren't launched until three years after pearl harbor, out of desperation as they lost air superiority, due to their aircraft becoming outdated and a lack of skilled pilots due to heavy losses during the war.

I guess the picture of him in his flight uniform right before he flew off, never to be seen again is a halloween costume then????

Just because one died in the Pearl Harbor attack does not make them a Kamikaze Pilot. In the attack on Pearl Harbor, a Japanese pilot's plane was damaged, so with no hope of making it back to his carrier, he deliberately crashed his plane into a hanger on Hickam Field. At this time in the war there were no official or organized kamikaze attacks or pilots. They were not organized until late 1944. It would make no sense for the Japanese, who had smaller numbers and finite resources, to deliberately destroy their prized air force. They had the element of surprise, superior airplanes, and highly skilled pilots. Pearl was mainly attacked with bombs and torpedoes. The first Kamikaze attacks were at the Battle of Leyte Gulf in the Philippines in October 1944. Purpose-built Kamikaze planes (Tsurugi's, Ohkas etc) were first used in March 1945. So while your uncle might have died, he wasn't likely a Kamikaze pilot.

Do you honestly believe that a single error always makes the entire statement invalid? Sometimes, maybe, but that's an awfully broad canvas you're painting there.
