The lie of "safe" air on airplanes:

STUDY finds that airborne transmission of #COVID19 dominated, accounting for a median of 92.2%, whereas contact (7.8%) and direct deposition (droplets, 0.0%) played minimal roles.

Passengers seated within two rows of the index case had a 4.41-fold higher attack rate compared with those farther away, but 45% of observed infections occurred beyond this proximity.
