I tend to agree with SeanJohnson that Traditional priests are a little too nonchalant about saying Mass outdoors. Indeed, there is great risk of sacrilege during windy conditions. There would have to be a proportionately grave reason (such as in the pictures from wartime). I think this is partly due to the fact that Traditional priests have become used to offering Mass in all kinds of locations due to being on the outs with the Conciliar establishment and not having access to the buildings that were once Catholic churches.
Now, one can never ... even in optimal conditions, completely prevent every single particle of the Blessed Sacrament from landing somewhere it should not. But I believe that God somehow takes care of these, sending angels to safeguard the particles ... or perhaps they even lose their consecration if they cease to have the accidents of bread. I've found the argument persuasive that if the particles are so small that they cannot be visually identified as bread (vs. a flake of skin or other substance), then since the accidents are no longer there, Our Lord is no longer in the particle, or, rather that the Lord is no longer the particle (lest my language suggest consubstantiation), i.e. that the accidents are not merely the chemical makeup of the bread, but also the appearance of being bread. I think that there can be a danger of scruples here. I could see a scrupulous priest examining the patent for several minutes after communion looking for every single tiny spec. Perhaps that is overkill? Could it lead to neurotic behavior?
