 | The Michelob Light Eagle and Daedalus human powered aircraft were testbeds for flight research conducted at the NASA Dryden Flight Research Center, Edwards, California between January 1987 and March 1988. |
| These unique aircraft were designed and constructed by a group of students, professors, and alumni of the Massachusetts Institute of Technology within the context of the Daedalus project. |
| Also in January of 1987, the Light Eagle was powered by Lois McCallin to set the straight distance, the distance around a closed circuit, and the duration world records for the female division in human powered vehicles. |

AIRCRAFT : Encyclopedia Entry (1962 words) |
| Fixed-wing aircraft generally use an internal-combustion engine in the form of a piston engine (with a propeller) or a turbine engine (jet or turboprop), to provide thrust that moves the craft forward through the air. |
| Heliplanes are combination aircraft with both a rotor and wings; they can take off and land vertically, and hover, like a helicopter, but use their wings for high speed flight. |
| The major distinction in aircraft usage is between military aviation, which includes all uses of aircraft for military purposes (such as combat, patrolling, search and rescue, reconnaissance, transport, and training), and civil aviation, which includes all uses of aircraft for non-military purposes. |
