NASA

Evolution of American Space Flight (10 pc set)
$18.99
I bought this toy for my 5-year-old son as a Christmas gift. As soon as we took the toy out of the box, one of the planes was missing some wheels. You couldn't see that the wheels were missing until the box was opened because of the packaging. One week after Christmas, several other space ships/planes have lost their wheels. My son has not been rough with the toys. I purchased two other space sets for him and their durability and quality has been fine. I would consider purchasing the toy again since my son is having such a good time playing with it and since he is able to learn more about space flight as a result of playing with them, however, I think that the construction of the toy in regard to the wheels is poor and needs to be improved.

Nasa: The Complete Illustrated History
$29.95
This is a great coffee-table book, and makes for great conversation. Got it for my dad for Christmas last year (2007) after finding out that he wanted to be an astronaut as a child. It's a large book, with a lot of really fascinating pictures. I can't speak for its technical merit, but it is a very interesting book.

Would definitely recommend :-D

I couldn't put this down. It changed everything I've ever believed about the space program. Buy it and prepare to stay awake into the night reading it.
