Back when my dad had his private pilot's license, we flew down to see my aunt once because there was a small airfield a short walk away from her house in a sort of suburban/exurban part of West Virginia. With all the time it took to get to the airport, get the plane, fly down, and walk, we didn't really save any time off of just driving, so we didn't do it twice, but it was novel.Residential Aerodromes are kind of common in semi-rural neighborhoods. There’s one about a mile from my house, which is about fourteen miles from downtown Portland, OR. When it was built in the 70s, this neighborhood was semi rural. Now it’s very suburban, but the aerodrome is still there.
She didn't have a personal airfield, though, which is what it seemed like Maria had in the movie.
