兄弟とも「妻と飛行機の両方は養えない」との理由で、生涯独身を通した。

Because they "could not both support wife and airplane" the two brothers spent their lives as bachelors.

Both brothers said that they couldn't support both a wife and an airplane, so they spent their lives as bachelors.

Saying they could not support both a wife and an airplane, the two brothers therefore spent their lives as bachelors.

The reason both brothers gave for remaining bachelors was that they couldn't support both airplanes and a wife.
