Boeing has agreed a $4.7bn (£3.7bn) deal to buy the parts supplier it sold nearly 20 years ago, as it seeks to improve safety on its production lines after a panel blew off an Alaska Airlines-operated plane mid-flight earlier this year.
The under-pressure US planemaker will buy Spirit AeroSystems, which supplies it with fuselage and wing parts, as it attempts to improve safety and quality in its manufacturing processes.
