I've an opportunity to fly either the L-39, the single engine jet fighter/trainer, or the historic British Spitfire. I can afford one or the other and I don't know if I'll have another chance to fly them again. Which would you fly? If cost is a concern, as it is most certainly is for me, the L-39 is about $3,800 an hour, the Spitfire about $3,600 for 30 minutes. Both will have about 10 mins taxi time. Any thoughts?
