More or less what you are describing is a common cargo plane, the workforce of the military. These planes were sold to Mexico as well, and could have
originated from there. As far as the numbers go, it's anyone's guess though I have flown in and jumped from those planes and never seen anything
like that before. If it was like the plane you displayed in the picture it was a C-17. If it seemed 'older' by having propellers, it was a C-130.
