Eighteen tanks with a 30-inch x 30-inch base dimension and heights of 48 and 60 inches of qualified crashworthy constructions were impacted from 65 feet. Nine of these failed adjacent to fittings on side panels. All tanks without side fittings passed the impact test regardless of constructions used and with average densities varying from 1.11 to 1.75. Indicated pressures were in the 130-150 psi range for two tanks of Firestone 1550-1 construction and 170- 200 psi for a reinforced, heavier revision of this construction.
