Years ago, I was launch pad OIC for a military missile launch at Cape Canaveral (Air Force side of Cape Kennedy). Got to see the thing launch from a few hundred yards away. Since this was a solid fuel missile, it was fast. You can't believe how fast it went.
A few years later, I was in grad school in Santa Barbara, CA. One evening, I saw a tongue of flame on the western horizon - a missile launch from Vandenberg AFB up the coast. Amazing....
Yes, these launches are a remarkable sight. Everyone should have the chance to see one at least once...
