Amazing suggestions guys, thanks! I'm definitely keeping track of the JF 747 because that's already bought in my mind.
Highly considering getting the DC-8 now, it seems perfect for every cargo flight I would ever do + the extra liveries Steve pointed out. It's also currently on sale on SimMarket. I was also not aware it was developed by someone other than Aerosoft's inhouse team.
Will look into the VL 727, I dont fly xp 11 a lot so I never looked into flyjsim but I loved seeing cargojet's 727 at my nearby airport back then so maybe that will motivate me 🙂
Once again, thank you all for helping me with this decision!
