Why did an unmarked Blackhawk rotor wash a supply drop off in western North Carolina
We were there Friday morning dropping off supplies and it was COMPLETELY FULL of supplies when we were there. However, we were met with mean and unkind people when we got there. Helos were constantly flying over, couple of Blackhawks with guys with AR’s hanging out of them. Now I’m sure they were military, but still, the whole vibe in that town was off…..we left there after almost getting robbed by the very ones “working” to distribute those supplies!!!
