What is Pax airship disaster?
[[File:Dirigeable Pax d'Augusto Severo 01.jpg|thumb|Pax [[Airship]] in 1902.]] The '''Pax airship disaster''' happened on May 12, 1902, in [[Paris]]. It caused the sad deaths of [[Brazil|Brazilian]] [[inventor]] Augusto Severo and [[French people|French]] [[Mechanics|mechanic]] Georges Saché. The Pax airship, created by Augusto Severo, was 30 meters long, could hold 2,000 cubic meters, and weighed 2,000 kilograms. Severo, a dedicated [[aeronautics]] student for 20 years, spent his fortune in the Pax airship, originally planned with an [[electric motor]] but later switched to [[Gasoline|gasoline engines]].<ref>{{Cite book|url=https://books.google.com/books?id=zgheCI0rZ5MC&dq=Pax+Airship+disaster&pg=PA82|title=Air Science: v. 1.

Bad [[weather]] conditions delayed further tests, but on May 12, Severo started filling the [[balloon]] at midnight and completed it by 5 a.m. Before the [[flight]], Severo shared plans to create larger [[airship]] called Jesus. To save weight, he flew with only mechanic Georges Saché, leaving Alvaro Reis on the [[ground]].{{sfn|''A Federação'', 11 de outubro de|1902|p=2|loc=Col. 4}}{{sfn|''Estado do Espirito Santo'', 18 de junho de|1902|p=2|loc=Col. 3}} Severo conducted tethered flight tests for twenty minutes, [[landing]] to converse with friends. At 5:25 a.m., he resumed the flight without tethering. Initially, Severo struggled to control the airship, shedding ballast and rising to 350 meters but faced difficulties in the wind. Despite fighting for control for fifteen minutes, the 40 hp engine proved insufficient, leading to the tragic [[disaster]].{{sfn|''A Federação'', 11 de outubro de|1902|p=2|loc=Col. 4}}{{sfn|''Diário de Pernambuco'', 11
