It has been there since 1996/7 which is when it last flew. I had a good look around it earlier this year, and are returning in March. Its condition is a little worn to say the least, and would require some intense restoration i would imagine.
If you ever get the chance to go to the Orlando area Fantasy of Flight is a great few hours out, very little flying apart from the odd stearman giving $60 jollies, but loads to see inside, and a few outside in the Florida sun.
At least the Sandringham/Sunderland is kept in the hangar.
