Good God. I've heard of beating a dead horse, but this topic has been going on since Reach launched. It is completely and utterly retarded to think that Humanities largest military colony would fall in one day. Most of the UNSC's strength was housed there. The SMAC's were on the other side of the planet, so they couldn't take out the Carrier. There would be differing accounts as to what actually happened, the navy might say that it fell in a day, but NOBLE was on the planet for a few months so that is what they would call "The Fall of Reach". Meanwhile the Navy is saying that the fall was only on one day, not over those months. Stop bringing this up.
