With the terrible loses sustained by US forces during D-Day on Omaha, I've always wondered why there was no coordinated close air support when the troops were pinned down by machine gun fire. When you consider the allies had total control of the skies, fighter aircraft could have strafed or "dive bomb" enemy positions at will. I'm pretty sure that marines and navy fighters worked together successfully during the island hopping campaign in the Pacific. If you think about it, it's just blitzkrieg the Nazis used just 5 yrs earlier. Anyway, those destroyers that risked running aground to provide artillery at Omaha had the right idea.
