Are planes safe during COVID?

Coughing, sneezing, singing, yelling and in non confined shared public spaces with no ventilation such as shared apartment spaces. What are your thoughts on aerosolization claims from non high velocity human sources such as normal breathing and speaking normally but a a distance and if there is a high percentages if this the replacement of air flow around and through the pours of cloth based mask carrying 5 micron particles in vectors even if diverted and not including higher risk high velocity sources producing and spreading further these 5 micron sources. What I mean if the air we breath not all being recycled behind barrier bethods and reused and needing air during exercice or with stress from circulatory conditions like blood pressure or heart or Lund damage/disease to move air with more carbon dioxide away the non projectile air having been claimed to aerosolize and spreading in different directions then forwards but still into the air in non controlled environments such as positive Ir negative pressure air flow isolation rooms found in healthcare.
