In an unexpected mid-flight incident, a Singapore Airlines (SIA) flight bound for Tokyo's Haneda Airport had to be diverted to Taiwan's Taoyuan International Airport after a crack was discovered in the aircraft's windshield. Flight SQ636, carrying 249 passengers and 17 crew members, took off from Changi Airport late Sunday night but had to alter its course shortly after due to the safety concerns posed by the damaged windshield. Flight SQ636, a Boeing 777-300ER operated by Singapore Airlines, departed from Singapore's Changi Airport at 11:07 PM on Sunday and was scheduled to land at Tokyo's Haneda Airport at 6:20 AM on Monday. However, about halfway into the seven-hour journey, the flight crew discovered a crack in the windshield. The nature of the crack and what specifically caused it has not yet been disclosed, but such incidents typically result from environmental stressors or manufacturing weaknesses that can be exacerbated during flight.
