An anonymous reader writes "The longest test yet of the technology that might one day lead to space elevators has revealed some unusual problems. From the article: "There were several unexpected encounters with wildlife. More than a dozen insect egg colonies had been laid on the tether and curious bats flew around the balloons, apparently attracted by the sound made by the tether's vibrations. Late in the test, swallows were also seen swooping down on the balloons, possibly to sip the morning dew on their surfaces." Maybe all the critters just want to go to space too."
