Whoever wanted the limit on number of Concorde need to have their eyes open. There are far more A380s in IF than in IRL and nobody is complaining about that. There is also more VC-25s in IF than IRL.
While IF aim to be a realistic stimulator, it will never be as real as in real life. We are playing with our iPad or phone while pilot use real yoke. Concorde should be open to everyone in IF since it’s such unique plane and it’s a gem to our eyes.
