An incident involving **Flydubai flight FZ1073**, which occurred on September 30, has sparked an investigation into the structural resistance of the **Boeing 737 MAX 8** aircraft. The incident gained significant attention on October 1, when former U.S. President Donald Trump commented on the event via his social media platform, **Truth Social**. Trump praised Boeing for designing an aircraft capable of withstanding G forces and constraints beyond those for which it was designed, calling it a "remarkable demonstration of precise and powerful structural planning and design." A former U.S. Navy pilot, mentioned in social media posts, claimed that the aircraft exceeded its maximum operational speed by 100 knots (approximately 185 km/h) while losing 20,000 feet (approximately 6,100 meters) of altitude in 30 seconds. However, flight tracking data from **Flightradar24** suggest a loss of more than 4,200 meters in 29 seconds, with a descent speed close to 9,400 meters per minute. According to a reconstruction by **ABC News**, the aircraft experienced a fall, a brief climb, and then another fall, losing more than 6,000 meters in a few minutes. The aircraft was flying from Dubai to Tel Aviv, at nearly 10,700 meters above Saudi Arabia. After transmitting emergency codes, including 7500, which signals an illegal intervention on board, the **737 MAX 8** eventually landed at the Saudi Arabian airport of Tabouk. The pilot and passengers are being hailed as heroes. Photos of the aircraft after landing show a large part of the rudder missing. The **Saudi National Transportation Safety Center (NTSC)** and the **Civil Aviation Authority of the United Arab Emirates (GCAA)** have opened an investigation. Neither Boeing nor the investigators have yet published an analysis of the incident. The **737 MAX** has a maximum operational speed of Mach 0.82, or approximately 875 km/h at cruising altitude. However, during the steep descent of flight FZ1073, the speed calculated by **Flightradar24** went from about 400 to nearly 600 knots (approximately 740 to 1,100 km/h), a level close to the speed of sound at that altitude. The **FAA**, the U.S. aviation authority, provides a margin above the maximum operational speed in its certification rules. The dive speed used in the design must exceed this by at least Mach 0.07, a margin that the manufacturer can reduce to Mach 0.05 if justified by calculation. The structure must also remain safe from flutter (self-sustaining vibrations that can tear off a rudder) up to a speed 15% higher than this dive speed. The fuselage of the **737 MAX** is made of aluminum alloy, like that of all **737s** since the first flight of the model in 1967. At Boeing, only the **787** has a carbon fiber fuselage. No G measurements during the dive of FZ1073 have been published, so it is currently unclear whether the aircraft exceeded the limits established by tests.
