8. Charles Pete Conradastronautastronaut who walked on moon on the Apollo XII mission in 1969 (third man to walk on the moon); space commander of Gemini XI, setting a world record in highest achieved altitude.
A Virgin Galactic rocket plane has reached the edge of space, the first US commercial human flight to achieve an altitude of more than 50 miles since the shuttle program ended in 2011.
Over-the-horizon radar systems are capable of localizing targets in range and azimuth but are unable to achieve reliable altitude estimation.
Other orientations are possible, such as the "80 Jump" takeoff which uses nacelles at 80° to quickly achieve high altitude and speed.
Three aerospike nozzles achieved good altitude compensation capacities in the tests and still had better performance at off-design altitudes compared with that of the bell-shaped nozzle.
Known as "Joao do Pulo" (Jumping John), he followed in the hops, steps and jumps of Brazil's great triple jumpers, and joined them in the record books with a distance of 17.89 metres, achieved at altitude in Mexico City in the Pan American Games of 1975.
Earning the Silver Badge shows that a glider pilot has achieved an altitude gain of at least 1000 m, made a five-hour duration flight, and has flown cross-country for a straight-line distance of at least 50 km: these three attainments are usually, but not invariably, achieved in separate flights.
But how many people achieve his career altitude without piling a few skeletons in the closet or, I don't know, underneath a homeless hostel?
ISAS is applying further effort to develop balloons with even thinner films, to achieve a higher altitude than 53 km.
Also known as "Birdman" or "flying squirrel" suits, this most awesome method of conveyance is primed to make the leap to the mainstream, especially considering the Manhattan skyline offers many skyscrapers that achieve the right altitude for takeoff.
He's not sure he quite views it that way although yes, he can understand why some may feel differently and yes, he can see the appeal of such stimulants; a little boost to achieve the right altitude.
