Several credible reports point to a cabin pressurization anomaly aboard United Airlines Flight UA770 as the likely reason for its emergency diversion. While oxygen masks didn’t deploy—suggesting no full decompression occurred—the issue was serious enough to prompt a precautionary diversion to London Heathrow, ensuring swift access to technical support and prioritizing passenger safety.

Numerous reliable sources are referring to an anomaly of cabin pressurization in the cabin of the United Airlines Flight UA770 as the probable cause of its distress diversion. Although the oxygen masks did not deploy, indicating that full decompression did not take place, the seriousness of the problem was enough to justify diverting the aircraft to London Heathrow as a precautionary measure, and to allow the aircraft prompt access to technical support, and where stringent priority was given to passenger safety.
