Task: Question Answering
Input (English): Passage: In 1943, a bombing mission by a Boeing B-17 Flying Fortress that had successfully dropped its bombs on target, has degenerated into an emergency situation over the Pacific. The navigator on board has not been able to plot a course back to the bomber's home base. The lives of the crew and the loss of the bomber depends on the skill and training provided for the navigator who represents a "weak link" in the crew.
The one solution to a lack of readiness to go to war in the air is the selection, testing, training and preparation offered by the Army Air Forces Officer Candidate School found in Miami, Florida. The motto of the school is Sustineo Alas (translated as "I sustain the wings"). The selection and testing to qualify is rigorous; after a physical examination, test scores based on general knowledge, and a stint as a corporal in command of soldiers, only 23 out of 1,000 candidates are chosen to proceed to the Officer's Candidate School.
All of the candidates have a diverse background and experiences, some as entertainers such as Robert Preston, while others have been successful in sports, business, science and academia. Many have also had combat experience as well as leadership positions. The twelve-week course stresses discipline, efficiency and restrictions that combine to instil all the attitudes and ethos of the officer cadre. 
Question: Which school's motto is translated as "I sustain the wings"?
Output (English): Army Air Forces Officer Candidate School.
