The mockup of the Original Hornet's flight deck that Doolittle first used in briefing the aircrews on how the B-25s would be positioned for takeoff is inside the Navy Air Museum, along with a 6 minute B&W reel footage film you can watch at the push of a button- a video cameo of one of the flight crews making its practice take-off run. Made by the War Department, for FDR to view when he was briefed on the progress of the pre-mission training.
a waist gun MG (de-milled) removed from one of those B-25's the morning of the strike, since they launched from so far away, all waist guns and all the ammo from the tail guns along with most of the flight crew gear, was removed to lighten the planes. - is also on display in the museum.
On the Hangar deck of the Hornet (as she is the Essex-class replacement for the one lost at Santa Cruz), is a B-25 which is at about 70% restoration (still requires a fair number of interior components and one of the engines is a non-working mockup), painted to resemble one of the planes.
One of my favorite displays is the original radio message flimsy from FDR to the aircrew that was read as they reached the 12 mile limit out from SF Bay on their way to bomb Japan. It is document preserved and encased, and hanging in a section of the Navy Air Museum as well. Interesting to read the words of encouragement that a President had for those men who volunteered to take a tiger by the tail.
I think "Yuri" might well enjoy what sits on the pole outside the museum main entrance (it is in the old Flight Ops building for NAS Alameda), - a "Fate" (F-8 Crusader), armed for bear and tilt wing extended as she would have appeared coming off a cat shot.
