(NEWSER)Â â€“ Malaysia Airlines Flight 17's black boxes have revealed that the plane was brought down by a "massive explosive decompressionâ€ after its fuselage was pierced by shrapnel from a missile explosion, a Ukrainian security spokesman tellsÂ the AP. "It did what it was designed to doâ€”bring down airplanes," a European air safety official tellsCBS News. The black boxes are being examined by experts in the UK. Britainâ€™s Foreign Office says evidence is mounting that the culprit was likely a "Russian SA-11 surface to air missile system, operating from within a Russian-backed separatist area in eastern Ukraine," theÂ Christian Science MonitorÂ adds.
