Why didn't the american 's see the Japanese coming?
This website is creditable because it is a ".edu" which is an educational based website (reliable because it is a non profit organization run website), the publisher and author's names are listed as well as contacted information.
This website explains what RADAR is and why it was hard for the Americans to see the Japanese air crafts before it was to late. A lot of people are quick to blame the US military for this attack, but it was really hard to see the Japanese coming, this website explains in depth why it was hard. "During the 1930s, all the major powers worked to develop usable airplane and ship spotting systems using radio waves. In 1942 the U.S. Navy began using the acronym RADAR, which stands for RAdio Detection And Ranging."
lack of communication
This website is creditable because it is a ".org" which is a non profit organization, so their info will be more accurate, and all of the hyperlinks work.
This website talks about the myths of WW2 and sets the readers straight on what actually happened. There is an article in here that talks about the misunderstanding and lack of communication between the US Air Force and US Navy that lead to the attack of Pearl Harbor. "Pvts. Eliot and Lockard were manning the radar at Opana Point. They noticed a large blip on the scope and call in to the as-yet not fully functional Fighter Information Center. Pvt. McDonald took the call and located the sole officer at the Center and asked him to call the operators back. Lt. Kermit Tyler, having ending his first tour of training at the newly established Fighter Control Center, received the report and, thinking it was a flight of B-17s due in from the mainland, told the operators to "forget it." The report went no higher than that. Interestingly enough, the new radars tracked the planes coming and going, but the Army did not tell the Navy about this pointer to the Japanese carriers until the 8th, a fact which quite possibly saved our carriers."
Hour by hour watch
This website is creditable because the date is written of its publishing and the hyperlinks work.
This website takes the reader hour by hour and describes what it was like being there and looking at all of the information that the American's saw when the radar began showing the Japanese approaching. "The carriers turn into the wind, and the first wave of planes—183 fighters, bombers, and torpedo planes—roar into the sky. Pilots reconfirm their navigation by using a Honolulu radio station’s music as a guiding beam."
