The REAL story was about two men. They erased Henry Coxwell and replaced him with a woman

This is the true story

"In 1862 the British Association for the Advancement of Science decided to fund a series of flights to study the upper atmosphere. The balloons would have to fly as high as possible. Member of the Greenwich Observatory and founder member of the British Meteorological Society, James Glaisher (1809-1903), volunteered to perform these potentially dangerous flights. In all he made 28 ascents between 1862 and 1866, 13 of which were funded by the Association. His usual pilot was the experienced balloonist Henry Coxwell (1819-1900). On their first ascent of 17 July 1862 they reached an altitude of 26,177 ft. without oxygen.

On 5 September, in a balloon called the Mars, they managed an altitude in the region of 30,000 ft., although it almost cost them their lives. Glaisher lost consciousness and Coxwell had to climb up into the rigging to free a tangled valve line. His hands were so paralysed with cold that he had to pull the chord with his teeth in order to check their ascent. Had he failed to manage it, they would both surely have died of hypothermia or oxygen starvation."

In the movie, Coxwell has been replaced by Amelia. Here you have the historical climb of Henry Coxwell to the balloon, with his hands paralyzed. But he has been deleted from his own story. Now it's female empowered Amelia who does it:

It seems that Coxwell doesn't deserve to appear in a movie that narrates his own achievements... because, well, he doesn't have a vagina. I'm sure he would be so happy about that!
