Lot of room? Compared to the Mustang, maybe. It’s like flying inside a leather swathed beer can! Oh, and I calculated that? the guy shown standing in the aisle must be 4′ 11″ (!) given the maximum height in the cabin is all of 68″…(I kid you not).
Damn nice plane, though, especially the newer ones with the winglets. Hauls ass and climbs like the dickens.
