Question:

Whhy didnt allies bomb Omaha Beach before D-Day? wouldnt that have saved thousands of american lives?

Best Answer - Chosen by Asker: They did, all along the coast to foil the Nazi strategists and Hitler, persuading them that they would land by Calais. But at that time bombs were dropped from very high, with very limited targeting systems and spread over a wide area. The thickness of the bunkers built on the beach lines, especially on Omaha beach, also meant that if those bombs levelled out the civilian houses they barely scratched the bunkers.
