In 1916, the brothers organized the Loughead Aircraft Manufacturing Company in Santa Barbara to build a huge 10-place, twin-engined F-1 flying boat for their aerial sightseeing business.[1] They began construction in a rented garage, which attracted the attention of 20-year-old John K. "Jack" Northrop.[3] Northrop was skilled in drafting and mathematics, and the Lougheads employed him in designing the F-1.[3]
