AN EXCELLENT CHILDREN'S BOOK BECAUSE IT HELPS CHILD CONFRONT LOSS AND POSITIVE THINGS CHILDREN CAN DO TO EXPRESS THEIR LOSS. PERSISTENCE, PERSERVERANCE AND DETERMINATION ARE IMPORTANT AS CHILDREN DESIGNED, BUILT AND FLEW THEIR MEMORIAL SPACE APPLE ON BOARD SPACE SHUTTLE DISCOVERY, STS-26. MANY PEOPLE (INCLUDING NASA) SAID THEY COULDN'T DO IT, BUT LATER, NASA ASSIGNED THEIR SPACE APPLE AS ITEM # 77 IN THE OFFICIAL FLIGHT KIT----IT FLEW! Yes, the children's hopes were up and the challenge was accepted! This is a super-great true story!!
