Review for LEGO set 6704 Minifig Pack from Brickipedia
“The set also comes with enough accessories to equip all of the minifigures. The equipment includes a metal detector, a walkie-talkie, a loud hailer, gripper arm, a jet pack (the new version from Blacktron II) and a combination of a wrench and a jack hammer. One of the M-Tron... More astronauts wears an old jet pack piece instead of air tanks.”
