TUI flight BY5442, which took off from Luton Airport at 9:30am on Thursday, 14th December 2023, en route to Lanzarote, had to divert to Gatwick Airport following what we believe was a windshield indicator alert. The flight was over the English Channel when the alert was triggered.
The crew, following standard safety procedures, decided to divert the flight as a precautionary measure. The decision was taken despite the absence of a formal emergency declaration.
