 With the thousands of extras battling on the ground, dozens of  airplanes flying around in the sky and hundreds of explosions going  off everywhere, the only two injuries on the entire picture were  incurred. One was by veteran stunt pilot Dick Grace (qv). A plane  he was crashing was supposed to completely turn over, but it only  turned partly over. Instead of being thrown clear of the plane as  was the plan, Grace was hurled against part of the fuselage and  broke his neck. He returned to the company after six weeks in the  hospital. The other was by one of the army pilots helping out on the  shoot. His crash was fatal and Wellman feared it would shut down  production, but the Army held the pilot, not the director,  responsible.
