Boeing says it has a fix for its Boeing 737 MAX 8 jet that is currently grounded worldwide. This relates to a software fix for the Manoeuvring Characteristics Augmentation System (MCAS), which is believed to have sent two planes into a fatal nosedive. This should be good news for travellers. Is it?

Airlines that are haemorrhaging money with aircraft idling on the ground – and shall have to spend yet more money on advertising and PR to reassure passengers their planes are safe – would be glad to get their birds in the air but not without solid evidence that the patch will work. The risks are too high.
