Small unproven operator in my opinion that tells us all they will change the world...
If you want to fly a Mustang go to either Blink or even better London Executive (LEA). But why do you want to fly on a Mustang in the first place? Operational restrictions? For the same money you can charter a nice CJ2 or 3 from an established operator and if it is a one way you might be better of on NetJets
