Hej Michal,
thanks for your reports and promoting Polish piece of aviation history.
Myself, I had a chance to visit Krakow and spend a day at the museum just this summer!
And what a coincident, I was just doing a slide show today with my pictures during our monthly IPMS meeting here in Houston, TX. Everybody seemed to enjoy it.
It's a bit different than just Mustangs and Corsairs, right...

Wish I could spend more time there to learn and discover even more of it.
I'll distribute a link to your story among IPMS folks too.
pozdrawiam & all the best
