Defeating the Aliens. Reverse engineering of Alien technology (particularly the saucer craft). I like a cigar and a beer in SHADO secure Bar unit with my trusted staff.
The Alien Leader. To end this war between our planets. With talk, or with my laser blaster!
Anything by the Geoff Love orchestra, but particularly "Space Themes". Nobody does it like Geoff.
2001: a space Odyssey. The actor who played the lunar shuttle pilot was particularly efficient. The Carry On films are also a great help during stressful missions; we have onboard DVD in the SHADO mobile personnel carriers.
Century 21 productions are a must. You can't beat Captain Scarlet for Super Marionation.
No time.
The human race.
