Droplet or Aerosol?
Influenza is thought to be transmitted primarily by droplets (particles ≥ 5 μm, and settling within 3-6 feet); however, the airborne route (particles < 5 μm remaining suspended in air) has been implicated in special situations, such as aerosol-generating procedures. Discussion has been ongoing between the US Occupational Safety and Health Administration (OSHA) and healthcare epidemiologists on the relative role of the airborne route, especially during the 2009-2010 influenza season with the emergence of the pandemic H1N1 strain.
Structure - EBOLA
In general, ebola virions are 80 nm in width, but vary somewhat in length. In general, the median particle length of ebola viruses ranges from 974 to 1,086 nm, but particles as long as 14,000 nm have been detected in tissue culture.
Structure - INFLUENZA
Influenza viruses A, B and C are very similar in overall structure.The virus particle is 80–120 nanometers in diameter and usually roughly spherical, although filamentous forms can occur

Can you provide us with some examples of truly airborne viruses?

Then, two weeks after the incident with the bloody glove, something frightening happened in the Ebola rooms. The two healthy monkeys developed red eyes and blood noses, and they crashed and bled out. They had never been deliberately infected with Ebola virus, and they had not come near the sick monkeys. They were separated from the sick monkeys by open floor. If a healthy person were placed on the other side of a room from a person who was sick with AIDS, the AIDS virus would not be able to drift across the room through the air and infect the healthy person. But Ebola had drifted across a room. It had moved quickly, decisively, and by an unknown route. Most likely the control monkeys inhaled it into their lungs. "It got there somehow," Nancy Jaax would say to me as she told me the story some years later. "Monkeys spit and throw stuff. And when the caretakers wash the cages down with water hoses, that can create an aerosol of droplets. It probably traveled through the air in aerosolized secretion. That was when I knew that Ebola can travel through the air."
From "The Hot Zone" (pg.65) a collection of true stories of Ebola outbreaks and close calls.
If you don't know what "extreme amplification" and "level 4" is you may want to read it..
Ultimately, we are all connected by the air we breathe.

SO, it is a picture. It doesn't mean that it was used there. If i have a picture of flying monkey's i put on the screen, does this mean we have to watch out for flying monkey's too. Click your heals together dorathy, the wicked witch is comming and the master is pulling the strings behind the curtains.

I'm only going by official gov documents and not news/media or their "experts" and feel free to correct me if I am wrong but to me this clearly says aerosol inhalation lungs.
Human-to human transfer usually occurs through direct contact with bodily fluids
from an infected individual though aerosol transmission can occur between individuals in close proximity
to one another

Huge difference between aerosol and airborne man.
Can you prove that by providing a viable link, because I am reading much different of Wiki and provided a link to my OP. But definitely open to anything more. Thanks in advance
Whether propelled by sneezing, coughing, talking, splashing, flushing or some other process, aerosols (an over-arching term) include a range of particle sizes. Those droplets larger than 5-10 millionths of a meter (a micron [µm]; about 1/10 the width of a human hair), fall to the ground within seconds or impact on another surface, without evaporating (see Figure). The smaller droplets that remain suspended in the air evaporate very quickly (< 1/10 sec in dry air), leaving behind particles consisting of proteins, salts and other things left after the water is removed, including suspended viruses and bacteria. These leftovers, which may be more like a gel, depending on the humidity, are called droplet nuclei. They can remain airborne for hours and, if unimpeded, travel wherever the wind blows them. Coughs, sneezes and toilet flushes generate both droplets and droplet nuclei. Droplets smaller than 5-10µm almost always dry fast enough to form droplet nuclei without falling to the ground, and it is usual for scientists to refer to these as being in the airborne size range. It is only the droplet nuclei that are capable of riding the air currents through a hospital, shopping centre or office building.
These cases may actively propel infectious droplets containing vomit and blood across the short distances separating them from caregivers. But this is a form of direct transmission, and is not airborne transmission.
Aerosol means cough/sneeze. Droplets in the air. A disease can spread yhat way and still not be considered airborne. Its considered airborne when the virus stays aloft for extended periods of time. Measles for example you can walk into a room where someone with measles is or has been and catch it. Cough and sneeze droplets are heavy and settle quickly.
