The issue is not only the masks and gloves but how you put them on and take them off.
Flying overalls are quite good as they are absorbent. They will absorb the fomite so as long as you remove them without contaminating your hands and leave them to dry for 24 hours you probably will be somewhat protected. But leather jackets on top add to the complexity. How do you don and doff helmets, and clean them, and after all that we have a picture of everyone huddled together potentially touching contaminated aprons.
We are now ever more aware that the severity of the illness is proportionate to viral load. In flight with vents open and side windows open the pilot is somewhat protected, and even the medical crew will be breathing low ppm. However, on the ground posing together for a photo just increases risk
Stay safe. Think before you touch. Assess if you can distance. Wash hands again and again
