Hi Cargo-one
I've been digging around on the internet today and you are correct , I was waiting to get flamed on this
I was told by a AN-72 seller in Russia a few days ago that an AN-72 would do it but I hadn't seen any perf charts yet
... all in all its a tough ask , difficult mission on a limited budget
There are some military Buffalos laying around here but the acquisition process is long and complicated however it may be the only way to get this job done with low initial capital cost
