Most near airports. Almost none while cruising at 30,000 feet at 600 mph. Most deaths from impact and fire. Sometimes enough warning to dump fuel. Almost all mechanical failure or human error.
Rest are bombings, weather, misc.
Same approach to train wrecks, bus wrecks, ferry boats, fires, earthquakes, storms, etc. Always keep key news values in mind. News is read by people. Story should focus on what happened to people. How get information on survivors, etc.
