FNG I hope that you are in a minority as to finding it odd. Its a machine and therefor seperate from its parent nations evil morality.There is no moral issue to be had here.Those who like airshows or just enjoy seeing planes fly could not fail to be facinated by the gawkish outline of a Stuka. As to those who might be affronted by its history and role in it, I suggest that a warning to the effect that 'this airshow contains content that might offend' should be posted
How can it be right to fly as many allied aircraft as can be made airworthy because we won.What is your stance be on restoration of B- 29's (Enola gay)
This article is interesting on that point

I reckon a JU 87 has several merits other than guzzling gas and it must have taken some balls to dive that lumbering beast to 350mph and rely on an automated device to pull out at 1500 ft at 6g regardless of who was in the sights during the war or the misguided conviction of its pilot if indeed he had any.
