Does Kermit Weeks count now?
In all seriousness, the older these gentleman get, the more private collections we will see for sale. That, or they will all be sold for scrap like some guys entire locomotive collection was sold for scrap by his wife after he died...
With regards to wrecks, if you want one, come to Florida. I made a list a few years ago (I haven't been here in awhile... Nice to be back guys

) that detailed a ton of wrecks from aviationarchaeology.com that probably weren't recovered. One was actually the crash record of a B-29 that ditched 4 miles off of Apollo Beach, FL, into Tampa Bay.
Of course I can't confirm if any of these actually exist or not, since I'm 17...
Ill try to find the list as I clean out my files.
