Falcons thought that COVID-19 does not impact us because we are flying high in the air.

But today, [this](https://www.google.com/url?q=https://www.ad.nl/binnenland/onderzoek-erasmus-mc-bevestigt-corona-via-lucht-overdraagbaar~a3c0322c/&sa=D&source=hangouts&ust=1588163291741000&usg=AFQjCNG4uwLh_mGglcSGCA2Buezsrox5pQ) was announced.

So yeah, Falcons need to use face-masks as well:
