Airline flight faults real issue

Flying has become quite unsafe , with  headlines of flights crashing or flights unexplained disappearance makes me wonder , especially with these Asian airlines.

Malaysian airlines (#MH370 & #MH17) and recently Air Asia #QZ8501 and recently #D7172 , luckyily that flight returned safe before anything worst could have happened.

Could we feel safe anymore flying... ?

Definetly hope so according to ICAO (International Civil Aviation Authority) one of their general responsibilities under their site http://www.icao.int/secretariat/Pages/ro-responsibilities.aspx stated they are responsible for "aviation security" and these responsibilities are again delegated to each regional representatives of the ICAO.
