One test crashed and literally blew up.
The Montgolfier brothers, Joseph-Michel and Jacques-Étienne, faced several challenges in their pioneering work on hot air balloons. They struggled with understanding the principles of buoyancy and thermodynamics, which were not well-developed at the time. Additionally, they encountered skepticism from the scientific community and the public, who doubted the feasibility of their invention. Safety concerns also loomed, as their early flights involved untested materials and methods, leading to risks of fire and structural failure.
The earliest form of a hot air balloon, created by the Montgolfier brothers in 1783, was made of paper and silk lined with taffeta. It was adorned with colorful patterns and decorations. The balloon was powered by a fire fueled by straw and wool.
The Montgolfier brothers, Joseph-Michel and Jacques-Étienne, are credited with inventing the hot air balloon in the 18th century. They successfully launched the first untethered manned flight in a hot air balloon in 1783.
The Lumière Brothers, Auguste and Louis Lumière, were pioneering filmmakers in the late 19th and early 20th centuries. They are credited with inventing the Cinématographe, an early motion picture camera, and are considered among the first filmmakers in history. Their short films, such as "Workers Leaving the Lumière Factory" and "Arrival of a Train at La Ciotat," were some of the earliest examples of cinema.

The Civil Rights Movement had some failures or partial failures in some of its objectives, including economic discrimination and poverty, although laws were passed. Some schools were integrated, but the neighborhoods were not.
