Speaking of the Collings Foundation, they now own another B-17G, which they are currently getting prepared to fly again (last flew in the 90's), which will temporarily take the place of "Nine-O-Nine". This new B-17G they now own is the one previously owned by/displayed at the Evergreen Aviation Museum - in addition to joining the Collings Foundation tour, once flying again it will also be receiving a new, authentic paint scheme. Once it joins the tour (as early as 2017 or 2018), "Nine-O-Nine" will be taken off the tour and will be treated to a much needed extensive overhaul over an expected two-year period. Once "Nine-O-Nine" is back on tour again, it is expected that Collings will likely sell this second/new B-17.
Also, the Collings Foundation has a new TF-51D that will be joining the tour this year, as early as this spring while the group is in California - the aircraft has been under restoration at American Aero Services and is just about complete. This TF-51D will be replacing the Collings Foundation TP-51C "Betty Jane" (very likely the most flown/traveled Mustang in the world, the last 9 years), which they will be selling.
