Airliners

A recent analysis by Boeing forecasts that unless safety is improved, jet airliners could be falling out of the sky at the rate of once a week by the year 2010.

Boeing, which builds more than half the world's commercial airliners, is understandably keen to draw attention to what can go wrong besides planes.

To fly big passenger airliners calls for long training and experience.

Most modern airliners use turbofan engines because of their high thrust and good fuel efficiency.

These airliners call business class "executive class".
