Tui Airways flight returns to Manchester after cabin pressure failure exposes passengers to risks

A Tui Airways flight from Manchester to Kos had to return midair due to a cabin pressure failure. An investigation revealed that maintenance errors left critical switches off, exposing 193 passengers to potential hypoxia risks. The crew did not detect the issue during pre-flight checks. Although the pilots turned the switches back on after the warning, they did not follow additional safety protocols, such as using oxygen masks, which could have mitigated risks. The cabin altitude warning remained active for 43 minutes before the captain decided to return to Manchester. The report highlights the importance of thorough checks and adherence to safety procedures in aviation.
