(2/2) Research was done for conditions without crosswind, headwind, tailwind. But when windy: same rule: stay out of slipstreams. Movie below: for running.

(3/4) Personal researcher déjà vu: Four of my previous aero studies, same type of response as now with #COVIDー19 : (1) 98%: "great work, well done"; (2) 1%: "we know this already"; (3) 1% "we don't believe it". #aerodynamics #CoronaCrisis #COVID19 #coronavirus #Covid_19

(4/4) Final results: other researchers reproduce our work & confirm our results. (2) and (3) sometimes insult our researchers, but after external confirmation, never apologize. Not much decency on social media, apparently. #patience #aerodynamics #CoronaCrisis #COVID19 #COVID

(5/6) Many misunderstanding apparently: If one reads our posts carefully, one will see we only indicate the equivalent of the 1.5 m distance in case people are not standing still but walking/running/cycling. This is aero work not virology. #Covid_19 #covid #Corona #coronavirus

(6/6) And that infection risk is larger when you inhale another person's droplets than when not, is the most basic common sense. Not sure what the criticism is about. #Covid_19 #coronavirus #Corona #coronacrisis
