Halifax, preferably the Hali III.
Realistically though, I'm looking forward to seeing a few Ansons, and the Duxford Beaufighter take to the air again. Agreed with the point above re BoBMF Spitsto a certain extent although it is nice to see the difference between the different marks. Maybe a few (pun not intended) could be sacrified to finance a Mossie rebuild.
PS When are they going to realise that there were no Dakotas or Lancasters in the BoB? Overdue for a name change methinks.
