Martin and Douglas spend most of their time together. They wake up together in the same bed, go to the same airfield, fly the same plane, and then come back together to the same house. There are brief moments of separation, when one of them flies solo, Martin goes out for drinks with Martin Davenport or Douglas goes to visit his daughter, but over the years of their working together and then being in a relationship, they got used to the fact that the other is always close - and they wouldn't have it any other way.

However, during one of the single pilot flights, one of them gets stranded alone (or with Carolyn/Arthur) in a foreign country - Gertie breaks down, Eyjafjallajökull erupts again, air travel is temporarily forbidden due to some political reasons - and begins to realize just how much one can miss their husband/partner/boyfriend. Cue angsty phone calls, nervous twitching at every bit of relevant news, heartbreaking moments when the other side of the bed turns out to be empty etc... And then, desperate reunion sex?
