I read a little on what they did to make it - I guess it only took around 10 or so photos to do - there is some type of special software/equipment that gets the job done quite easily I believe.
Skyhawk, yep, all work has been focused on D-model type Mustangs at this time. There is no decision right now about the dorsal-fin variants of the B/C models coming over to FSX, but I certainly think it's an eventual-possibility. There will have to be some other things done before that will happen however.
By the way, for those that may not know, the vice-grips are there in the cockpit, incase the gear handle were to break. Originals are known to break, while there are reproductions that are much stronger and less likely to do so.
