Don't know if this is for real, but certainly, if the CHAZ gets access to a dedicated chopper, that would help them resupply even if the City blocks off surface traffic.
"Hey guys my dad owns a popular helicopter charter company just outside of Seattle. He’s a massive supporter of BLM (being of color himself) and wants to help out in some way. Since his company has achieved a rather high profit margin this financial year, I’ve convinced him to donate one of our helicopters to CHAZ for the people to do with as they wish. Are there any times and places that suit for a drop off of the donation? PEACE "
