A Roman toilet amid the ruins in Ostia, Italy. The Romans' plumbing technology probably could've come in handy during the Dark Ages. Although certain documentaries are fond of trotting out ancient aliens or other fringe theories to explain our ancestors' advancements, in truth, we need reasons no more far-flung than the fact that ingenuity is humanity's oldest quality. Left to our own devices and allowed to exist without constant fear of death by hunger or violence, we devise some startling stuff - even if some of our better efforts don't outlast our calamities. Then again, sometimes they do.

Fixed-pitch blades helped to reduce the number of moving parts at work on the earlier models. However, the downside of fixed-pitch blades is that they cannot be adjusted during flight. Being the latest model, the Springtail EFV-4B now features several technological upgrades and improvements -- including variable-pitch blades. Another major improvement is the Springtail's new control system. A pilot could operate the original XFV prototype using two hand-control grips and control arms, and by shifting his or her weight from side to side. However, after applying that operations concept in the wind tunnel at the NASA AMES Research Center back in 2000, the testing team discovered that kinematic (body) movement was not going to allow the pilot sufficient control of the craft. Currently, the Springtail uses fly-by-wire controls. In theory, this system is somewhat like the drive-by-wire systems designed for concept cars such as GM's Hy-wire. The operator controls the vehicle using two joysticks, one for each hand.|Landscapers pondering their next move. See more pictures of annual flowers.
