A portal was made underground which made them able to do time travel and communicate with other types of life. They had a time tunnel which allowed them to contact the aliens. Using time travel, they went back to 1943 and flying saucers from aliens were sucked into the lab. The aliens demanded a special type of quarts to get their engine fixed for the flying saucer. However, they simply used the time machine to get another flying saucer from another planet.
