Toronto, March 13: The UK has joined a growing list of countries that have grounded the Boeing 737 Max after the Ethiopian Airlines crash that claimed the lives of all 157 people on board. The UK was preceded by Ethiopia, China, Singapore and Australia grounding the Boeing 737 Max aircraft pending review.

The UK's Civil Aviation Authority (CAA) said the Boeing 737 MAX were not allowed to operate in or over UK airspace "as a precautionary measure". It said it took the decision because it did not currently have "sufficient information" from the flight data recorder about the fatal crash over Addis Ababa. The UK’s CAA announcement resulted in a Turkish Airlines flight to Birmingham having to turn around and return to Istanbul.

In the aftermath of the accident, France, Ireland, Germany, Indonesia, Malaysia and India have all temporarily suspended the 737 Max.
