Am I the only one who fails to see the relevance of whether pilot(s) are single, married or in a committed long-term relationship?
On an unrelated topic, a counter argument to prospective solo operation of commercial air transport might be to consider further multi-skilling of first officers. All that unnecessary spare capacity (in between in-flight crises) could perhaps be employed in other on-board areas, such as children's entertainer, or singer-pianist at the A380's walk-up bar lounge?
