Neither ship had sustained any significant damage. The aircraft however, sustained substantial damage. Attacks, even if successful, often sustained severe casualties. Shooting halted temporarily as both had sustained injuries. Nonetheless, some players still sustained injuries. He sustained a hamstring injury and missed three games. However, he sustained a foot injury and withdrew from the squad. Taroon was killed but Amin only sustained an injury and escaped. Thus, both had sustained damage, albeit temporary. Worse, output levels greater than formula 41 cannot be sustained for long. This has not been sustained by subsequent investigations. Adamson sustained serious injuries during the ditching. They could only be sustained by constant immigration. As a result, the cycle cannot be sustained indefinitely. Seemingly paradoxically, these are sustained through increases in energy efficiency.
