Subject: the tracks run in trenches 2 meters deep Из описания NASA crawler transporter:The eight crawler tracks were adapted from tand design. Each track is 12 meters long and 3 meters tall. The tracks run in trenches 2 meters deep. Что-то не поняла про траншеи... он их просто может преодолевать? |
