Re: Let's be different
Mechanics looking after historic racing cars have seen everything and are very difficult to impress. One thing that pulls them out into sunlight is the sound of a Merlin engine.
I propose Spitfire replicas for the Red Arrows. The rest of a new run of Merlin engines would be available for replica Hurricanes and P-51 Mustangs.
When we watch a display of restored or replica WWII aircraft, we rarely see the performance of which they were/are capable. A genuine plane is simply too old to pull the number of Gs as when new. Replicas are usually disallowed owing to insurance or legal limitations.
