Sky, whose real name is Skyraider, was on the first reconnaissance team to enter the Pentagon on 9/11/01. There was still heavy fire and intense draft heat, but she went in focused on doing her job. She is a small dog, but she has a big heart.

Bob Sessions, a real estate agent in Dickerson, MD was in the first FEMA team to arrive at the Pentagon. He's working with a 5-year old black Labrador Retriever named Sky. This is Sky's first major incident, but Sessions has been doing search and rescue work for 17 years.

Sessions and Sky entered the Pentagon while it was still on fire. "Of course, it was dangerous and it was very hot," he says on his cell phone, while standing only a few feet from where the airplane plowed into the Pentagon. "We climbed to the second floor to look for survivors. Before entering the search area, I placed Sky on a 'sit/stay' and then I proceeded to insure his safety the best I could. In reality our lives depend on one another, but that's what we train for."

Sessions adds, "If these dogs only knew what a difference they make. Certainly, there's nothing that can replace precision of a dog's nose - and absolutely nothing that can replace a dog's heart."
