Capture the Flag

Mike Goldwing is a kid whose grandfather Frank was meant to fly to the moon on Apollo XI, but his baby son (Mike's father) got sick and Frank had to pull out. Blaming his son for the frustration of his whole career he has distanced himself from the family. When Richard Carson, a Texas billionaire, plans to fly to the moon and destroy the Apollo XI flag, Mike determines to stowaway on the rocket to help frustrate Carson but above all ensure at least one Goldwing gets to the moon.
