AAIB added that window panes were “deformed and shrunk[en]”.
The Titan Airways plane is used by TCS World Travel, an American luxury holiday company, the report said.
Narrating the incident in its report, AAIB said that a crew member saw that one of the windows was “flapping”. At that time, the plane was at an altitude of 14,500. AAIB also stated that “the cabin had remained pressurised normally”.
“Whereas in this case, the damage became apparent at around FL100 (10,000 feet) and the flight was concluded uneventfully, a different level of damage by the same means might have resulted in more serious consequences, especially if window integrity was lost at higher differential pressure,” read the AAIB report, as per the Independent.
