All was going ordinarily well until Icelandic airspace was reached, that was when it all changed.
An unexpected volcanic eruption followed by dual engine failure and the sudden teleportation into Equestria all happen at once, the pilots of the Airbus A318 under the callsign Golf Echo Bravo are speechless, not only are they gone from earth, but they find themselves in a country inhabitated by mostly ponies. The stay was certainly unexpected, but now they face the reality they may never return home.
Back on earth, an international investigation team is scrambled between Iceland, France and the United Kingdom, however even they find themselves dumbstruck at the case initially. Progress is slow, but over time, interesting pieces begin showing up along the way.
The puzzle unravels slowly, as the adventure follows both an Equestrian & Earthly POV.
