But can Boeing do a Knife edge Loop?????















Boeing Successfully Flies Fuel Cell-Powered Airplane

Boeing has, for the first time in aviation history, flown a manned 
airplane powered by hydrogen fuel cells. The recent milestone is the work 
of an engineering team at Boeing Research & Technology Europe (BR&TE) in 
Madrid, with assistance from industry partners in Austria, France, 
Germany, Spain, the United Kingdom and the United States.
A two-seat Dimona motor-glider with a 16.3 meter (53.5 foot) wingspan was 
used as the airframe. Built by Diamond Aircraft Industries of Austria, it 
was modified by BR&TE to include a Proton Exchange Membrane (PEM) fuel 
cell/lithium-ion battery hybrid system to power an electric motor coupled 
to a conventional propeller.
Three test flights took place in February and March at the airfield in 
Ocaña, south of Madrid, operated by the Spanish company SENASA. According 
to Boeing researchers, PEM fuel cell technology potentially could power 
small manned and unmanned air vehicles. Over the longer term, solid oxide 
fuel cells could be applied to secondary power-generating systems, such as 
auxiliary power units for large commercial airplanes. Boeing does not 
envision that fuel cells will ever provide primary power for large 
passenger airplanes, but the company will continue to investigate their 
potential, as well as other sustainable alternative fuel and energy 
sources that improve environmental performance.
