there is no public beach access to these wrecks since the beach access is owned by ME, your local US tax payer. And of course for some reason the caretaker, oh what a oxy moron this will be, is the USAF. Yep the beach access is part of the Vandenberg Air Force Base. I got a look see when my sis was stationed there a decade or two ago. Got to walk around SLC-6 (slick six, which was intended to launch the Space Shuttle - it has been torn down and rebuilt for Delta III and IV style satellite launches.
As for Honda you can get a good look from the bluffs around the area. Before airplanes were running into high rise buildings you could get limited access to them from the ocean, say Santa Barbara for big boats, if there was going to be a luanch you would get run off. As for collecting brass... well you will have to talk to the rapers and pillagers at the previously mentioned California Wreck Divers site. The Navy still considers those wrecks theirs and the local military takes pride in taking away any brass that divers may bring up. That does not mean that some of the "historical preservationists" have not been able to obtain some of the brass.
There are quite a few books about the disaster and the proceeding from the trial of one of the captins that did not follow orders.
By the way the flowers in Lompoc, Vandenberg's city neighbor, are in bloom and quite wonderful to see. You have heard about the corn fields in the mid west - Lompoc is known for their flower fields.
