It would be cool if they found an He-111 there. My guess would be later planes though, hopefully they find some examples of a ME-262, Long Nosed 190, or He-162.
Anything jet or technically advanced ( like the incomplete Hs 132) would have been carted off by the Soviets.
Henschel Aircraft had a huge complex there; above and below ground. Ju-88s
and Ju-388s were built there up until Feb '45 when all production switched to single
engine fighters. Plus all the Henschel guided missile projects were built there, which
could account for large quantities of SC500 and other type bombs.
Anything from He-111s, Do217s, Ju88/388s. Fw190A/D/F/G's
Me109G/K's, Hs129s, or Ju87Gs. Who knows.
I ran across a site earlier where a Soviet pilot shot down
a Me-109 over Schoenefeld in April '45 so they were probably based
there during the last days of the war.
