Yes, Frederick Jones, a black inventor, patented an air conditioning unit for refrigeration systems in 1949. His invention revolutionized the transportation of perishable goods and improved the comfort of buildings, vehicles, and more.
A man cannot naturally float in the air without assistance from external factors like technology or equipment such as a hot air balloon, paraglider, or airplane.
A police office named William Potts of Detroit Michigan in 1920 invented the traffic signal. His race is not mentioned.
The man falling out of an airplane with a parachute is experiencing fluid friction, as the air molecules slow down the descent of the parachute due to air resistance.
When an object falls through air, it experiences air resistance. This air resistance is a force that opposes the object's motion. The amount of air resistance an object experiences depends on the object's shape, size, and speed. A man using a parachute falls slowly because the parachute creates a large amount of air resistance. A stone falls very fast because it has a small amount of air resistance.
Frederick McKinley Jones
Nope. It was a white guy. Martin Cooper in 1973. Nor did a black man invent the air conditioner, peanut butter, ice cream, traffic light, and a host of other poorly researched self esteem building myths that pop up in schools and local news pieces every February!
no
In short, no.
yes
You call a Fix it man

Willis Carrier was the man who invented the Air Conditioner in 1902.
HE WAS THE FIRST BLACK MAN THE INVENT NEW FLAVORS OF ICE CREAM.
If your air conditioner is acting up first check to see if the problem may just be that its dirty. If its not working at all then it will be necessary for a repair man.
It has made man cooler during summer. It has the ability to cool the air, therefore making man kind cooler when using an a/c.
