Safety concerns raised for other Boeing plane models
This time it is the popular 787 Dreamliner.
A whistle-blower has told the BBC, passengers could be left without oxygen in case of a loss of cabin pressure. A former quality control engineer says about a quarter of the planes’ oxygen systems fail to deploy properly.
Meanwhile, Boeing’s 737 NG is also facing problems, with dozens now grounded worldwide. Ryan Air is the latest to suspend some of its planes after finding cracks in their wing structure.
Alex Macheras, an aviation analyst in London, talks to Al Jazeera about the developments.
