Si Fly Flight 3275 were found in good condition. Analysis from the crash site concluded that the plane struck tree tops first before impacting terrain. The first impact occurred 15 metres from the top of a ridge, in a rocky mid-mountain area. During the impact, the fuselage and wing disintegrated, the fuel ignited, and an explosion occurred.

Weather front Weather front A weather front is a boundary separating two masses of air of different densities, and is the principal cause of meteorological phenomena outside the tropics. In surface weather analyses, fronts are depicted using various colored triangles and half-circles, depending on the type of front. The air masses separated by a front usually differ in temperature and humidity. Cold fronts may feature narrow bands of thunderstorms and severe weather, and may on occasion be preceded by squall lines or dry lines. Warm fronts are usually preceded by stratiform precipitation and fog. The weather usually clears quickly after a front's
