In horrific news, Malaysia Air flight 17, a Boeing 777 flying from Amsterdam to Kuala Lumpur, crashed after being shot down. People are suggesting it could have been shot down either by Russia's built-up air defense apparatus along its border with Ukraine or by pro-Russian separatists with a mobile radar-guided SAM systems. How possible are these scenarios?
Within the last few days, two other Ukrainian aircraft have been shot down in similar fashion and just hours ago, a Su-25 "Frogfoot" close air support aircraft flown by the Ukrainian Air Force was shot down over Eastern Ukraine by what was surmised to have been a radar-guided surface-to-air missile. The pilot ejected safely.
