Was looking over the impressive list of aircraft that are set to attend The Gathering of Mustangs and Legends. Noticed a couple of interesting P-51 attendees. Looks as though The Fighter Collection P-51 will be attending the show. I imagine it will not be flown over the Atlantic, or will it?
"Boomer" is another new addition. This aircraft must have flown recently, there is even a photo of it in formation with other North Dakota based P-51s. Anyone have further info as to its first flight?
Finally I was very surprised to see the addition of the XP-51G "Marjorie Hart" I have not heard much on the restoration of this aircraft. Any photos out there of this aircraft? Is it really that close to flying?

Thanks.
