Private airline companies have always been determined to operate a transport system that is safe for passengers, whilst still remaining competitively priced and commercially viable. However, a private sector business can only remain viable if it generates profits for its shareholders. Recent reports suggest that if all aircrafts were fitted with military derived Ground-to-air missile defence system, and at all airports there was infallible screening for weapons and explosives then the system would be much safer.
