Dose anyone know of any WWII Aircraft that can be tracked?
Check this discussion.
Remember, please search the forums first. (this discussion found using “warbird” in the search)
Ok, Thanks. 
You can view all airborne aircraft by type by using this link:

Most WWII aircraft would not be flying IFR though, so you’re going to have a hard time finding one on there.
If you have a specific aircraft type in mind you can find it there. Bear in mind that you might need to look up the type designator of the specific model you’re looking for. (you can find a listing, here among other places). Many are quite obvious, like P51, or ZERO, but some are not perfectly intuitive.
Edit, I type too slow.
Do you think they are trying to avoid radar?
Nah. Weather conditions [and pilot rating, of course] will make the difference whether one will fly IFR or VFR. Pilots owning WWII planes fly them for the pleasure of flying these warbirds. Therefore, there really is no reason for them to fly in marginal conditions.
All the warbirds are so expensive to fly and maintain,like above they do not want to risk flying in anything other than ideal conditions,one way to track a few is to check an airshow schedule for various airports and check the arrivals and departures for that airport.LAst week there was a show at ANDREWS AFB and a B-17,B-25 and P-51 were trackable.
The EAA’s B-17 arrived at BFI on a flight plan: flightaware.com/live/flight/N5017N
I’ve tracked a few with my camera and shot hundreds of photos. It’s very time consuming to post the photos online but here are a few I’ve taken over the last 2 yrs:

And here’s a sugn posted inside a Junkers Ju-52:
Cute! Love it! 
Funny sign. I still can’t believe anyone took my post seriously! 
Got this email from my Norweigan buddy a while back. Pretty clever.
