For the Knife Flights, I used the red plane from the Airstrip (the one used for Arms Trafficking). The majority of the KFs are easy, but there are some really frustrating ones, like the one where you have a gap that is only slightly wider than your actual plane, and one where you kind of slither around the building.
Abusing the Quick Save feature is a massive help while attempting them, because you will die quite a few times.
I guess people overlooked the two posts I put about the Knife Flights, because the one with the gap that is slightly wider than your plane doesn't need to be flown through to get that one. The buildings that are a part of that gap work for that flight.
