So far the series has been on air force one and on marine one.
It gives the viewers a rare if not exclusive glimpse behind the everyday workings of air force one and marine one's operations.
I thoroughly enjoyed the air force one episode so am looking forward to the second :).
Thought i'd give you the heads up.
Also for those who have children there is a print out to make a model 747 air force one out of paper and a simple paper aeroplane :D
