In 1921 Ocker was named to a Board of Inquiry investigating the much-publicized crash of an Army aircraft on 28 May 1921, with 7 fatalities, following a review of the air brigade at Langley Field. The airplane was returning to Bolling Field in the DC area when it was caught in an intense storm. Ocker was also flying home from the same function and had also encountered the storm; this involvement was publicly noted by the Army when it made the press announcement naming Ocker and the other board members.
