Instituting vigorous measures to correct past training deficiencies, he established the airship training program on a sound basis and set up from 75 to 100 experimental projects in the general categories of flight, engineering, electronics and laboratory. In addition, from 10 September 1943, as Special Assistant (LTA) to Deputy Chief of Naval Operations (Air), he was the principal advisor on lighter-than-air matters.
