I don't know if you're in the US but I know these guys like to do tours of the States, although they've been on hiatus for a bit. Unfortunately they lost their B-17 to a deadly crash. They actually offer "flight lessons" in the only P-51D originally built as a two-seat trainer left. It costs a lot but I mean... it's a fucking P-51! Hope they can get back to doing their awesome tours again.

After reading that Wikipedia article further it seems the FAA revoked their certification to carry passengers and that explains the hiatus. Hopefully that can get resolved. Or they could continue flying the aircraft around the country and just show them to people on the ground, which they already did. It's pretty cool to climb through them! I was actually afraid of something like the 2019 incident happening so I didn't go up on a flight.
@pfunk - Wow - they had B-17 too and they do flying lessons in a Mustang - wow wow wow. Wish I was in the US. Well some day, I will save enough money to be able to travel and see these beauties. You are so lucky to have been able to climb through them. Must have been awesome. I hope the FAA certification issue gets resolved soon.
Thanks for providing so much info. Really enjoyed this.
