The Harrier is the offspring of a Cheetah and Chasseur. Engineers at Paxton were so impressed by the NuCoal gear that they immediately lobbied for the opportunity to develop something similar. Though they were never able to solve the fuel economy problems that plagued the Chasseurs initial design, they were able to sidestep the problem by mounting the hover system on an ultralight chassis.The Harrier is the preferred gear for recon specialists who need to be able to extract themselves from any situation quickly.
