Returning from yet another test flight, this beautiful Turkish Cargo Boeing 777 emerges from the clouds and makes beautiful landing on a soggy runway after performing a go-around from an ILS Runway 16R Missed Approach. During the first approach you can see all landing gear doors are open, and the Ram Air Turbine - RAT - extended. This is a normal occurrence here at Paine Field due to the pre-delivery test flights. The doors indicate that the landing gear was extended using the auxiliary landing gear extension which unlocks the doors, allowing them to just free-fall into the open position, which is done in the case of a hydraulic system failure. The RAT is extended as a wind-driven backup for the hydraulic system.
