This is a good definition of true airborne -- aerosolized particles, which Ebola is not. Something like weaponized Anthrax IS.
"a draft or gust of wind could carry droplets a considerable distance."
A good definition of extended droplet dispersion which is not the same as airborne dispersion, according to formal definitions. Still deadly, though.
Goofing around with technical and possibly misleading definitions is just one of the variations of the hubris that will get people killed.
If it isn't airborne, it is damned sure airmobile.
