My biggest annoyance about watching WW2 films is open voice radio communication over long distance. It's worse than anachronistic marks of Spitfire. Yes I am being serious

Also there was no mechanical feedback between aircraft guns and their triggers (sure the whole aircraft shook like billy-O, but the pilot didn't pump his hands like he was holding a pneumatic drill)

I find these sorts of mundane things interesting, but they could be really important. "Wireless" (Morse) signals could take hours to be received even a few hundred miles away. Or not at all! Even then it could take hours to decode and get them onto the eight desk

Ships at sea still communicated by flags or signal lamp, preferentially the former if there was a chance an enemy could see them. They were reluctant to transmit over radio as it might give away their presence even if the signal couldn't be decoded

And there was the ever present danger of the centre trying to guess what was going on based on scant or out of date information and transmit countermanding orders to ships that were deliberately maintaining silence

Anyway, I'm watching Midway and the signal "Scratch one Enemy Flat Top" has just been received over a loudspeaker in an operations room. Where to even begin?! For a start, the signal was sent during the Battle of the Coral Sea

The signal was sent in Morse. It would have arrived in the operations room as a slip of paper. That would be much more fun to show for audiences, right?

The Japanese are at it too. They just discussed which pilot's voice they could hear over a loudspeaker on the bridge. It's debatable the Admiral would even have been on the ship's bridge

The USS Yorktown is currently being commanded by Charlton Heston. Who is a middle ranking pilot...

They obviously ran out of money as they are using stock footage from "Tora Tora Tora!". The Japanese aircraft are hundreds of miles out in the Pacific Ocean and the dock cranes of Pearl Harbour are right behind them in the shot
