Jean-François Pilâtre de Rozier became the first human to ascend on a hot air balloon on 15th October 1783 . He piloted the tethered Montgolfier brothers’ hot air balloon to a height of 80 feet. FYI, according to some reports, it was Étienne Montgolfier who made the first human ascent.
Rozier became the first air casualty along with Pierre Romain. In 1785, as the two were trying to cross the English channel, their hot air balloon exploded, killing them as a result.
The first program to incorporate WYSIWYG technology was Bravo. This document preparation program was developed for the Alto computer designed at the Palo Alto Research Center of Xerox. Though Bravo was never released commercially, its direct descendant was included in the Xerox Star. WYSIWYG, Ethernet, GUI, bitmap graphics and several computer technologies that we used today have been developed at the Xerox's Palo Alto Research Center (PARC). [more...]
