A TUIfly Boeing 737-800 aircraft had to return shortly after takeoff in Frankfurt am Main for safety reasons on two consecutive days. This was confirmed by a spokeswoman for Fraport AG. The first incident occurred on Wednesday on a flight to Heraklion in Crete, the second on Thursday en route to Gran Canaria. Both times the aircraft returned safely to Frankfurt. The exact reasons for the emergency landings remained unclear, and the airline was requested to comment.

"The situation at Frankfurt Airport was further secured by the presence of the fire brigade, which is routinely called in for potential technical issues. This incident is part of a series of problems that have troubled Boeing in recent years, starting with the tragic crashes of two 737 Max jets that claimed the lives of 346 people."

This series of incidents led to the US aviation authority FAA intervening again, particularly after an incident in early January 2024, in which a fuselage part of a nearly new 737-9 Max broke off during a flight. Subsequently, the FAA ordered that affected aircraft are not allowed to take off until technical inspections have been carried out and scrutinized Boeing's production and inspection processes. The ongoing problems not only burden passenger safety but also the confidence in the aircraft manufacturer, which is trying to emerge from a deep crisis of trust.
