Here's the full surveillance video showing moments before the Lufthansa Boeing 787-9 (D-ABPQ) nose gear collapsed at Frankfurt. If you watch closely, the nose landing gear doors open first, indicating what appears to be the start of a normal landing gear retraction sequence. According to reports, the Dreamliner had logged a maintenance request the previous day involving a landing gear door error message. On the Boeing 787, maintenance personnel can place the aircraft into a special maintenance mode (on the overhead panel, turn switch to "enable"). Boeing manuals emphasize that if maintenance mode is enabled, hydraulics are powered, and the gear lever is selected UP, the landing gear can retract regardless of weight-on-wheels protection. To prevent this, there's an override button where the gear handle lockout can be bypassed to move the gear handle even if it is locked out. The only way this can happen is by intentionally bypassing the normal safety lockouts used during maintenance procedures. Outside of maintenance or certain emergency procedures, the aircraft's weight-on-wheels system prevents gear retraction on the ground. Lufthansa says the aircraft has since been recovered. Fuel was removed, the jet was lifted, the nose gear was re-extended, and the aircraft was successfully towed under its own weight to a maintenance hangar. Germany's Federal Bureau of Aircraft Accident Investigation has completed evidence collection from the aircraft and is now gathering witness statements. An interim report is expected within approximately 8 weeks. 📹: airlinersde via YouTube, link on first comment here.

NEWS: SpaceX has released a statement after today's successful 11th Starship test flight. "Every major objective of the flight test was achieved, providing valuable data as we prepare the next generation of Starship and Super Heavy. The flight test began with Super Heavy igniting all 33 Raptor engines and ascending over the Gulf. The successful first-stage ascent was followed by a hot-staging maneuver, with Starship’s upper stage igniting its six Raptor engines to continue its flight to space. Following stage separation, the Super Heavy booster completed its boostback burn to put it on a course to a pre-planned splashdown zone off the coast of Texas using 12 of the 13 planned engines. Under the same angle of attack tested on the previous flight, the booster descended until successfully igniting all 13 planned engines (including one that did not relight during the boostback burn) for the high-thrust portion of the landing burn. The booster successfully executed a unique landing burn planned for use on the next generation booster. Super Heavy hovered above the water before shutting down its engines and splashing down. After completing a full-duration ascent burn, Starship achieved its planned velocity and trajectory. During flight, Starship successfully deployed eight Starlink simulators and executed the third in-space relight of a Raptor engine, demonstrating a critical capability for future deorbit burns. Starship re-entered the Earth’s atmosphere and was able to gather extensive data on the performance of its heatshield as it was intentionally stressed to test the limits of the vehicle’s capabilities. In the final minutes of flight, Starship performed a dynamic banking maneuver to mimic the trajectory that future missions returning to Starbase will fly. Starship then guided itself using its four flaps to the pre-planned splashdown zone in the Indian Ocean, successfully executing a landing flip, landing burn, and soft splashdown. Focus now turns to the next generation of Starship and Super Heavy, with multiple vehicles currently in active build and preparing for tests. This next iteration will be used for the first Starship orbital flights, operational payload missions, propellant transfer, and more as we iterate to a fully and rapidly reusable vehicle with service to Earth orbit, the Moon, Mars, and beyond."
