More News : With three major plane crashes in a week, it seems air disasters are happening very frequently at present . More than 3 billion people took to the skies last year, with only 210 fatalities.

The three airliner crashes in the last week have claimed nearly 450 lives.

An Algerian aircraft carrying 110 passengers and six crew crashed in northern Africa early on Thursday
