The so-called Spitfire Mk26 is simply a scale model of the true aircraft.
Just as the Isaacs Fury was a 70% replica of the original Hawker Fury, this 'Spitfire' is a 75-90% replica of the original Vickers-Supemarine Spitfire.
To pretend that 'the Mk26B is a new mark of Spitfire from Supermarine' is simply self-delusion.
When is the 'Spitfire squadron' at Enstone now expected to take to the air? I wish them the very best of good luck, but I'm afraid that I have my doubts.
