Matt McSwain says the group has more than 90 helicopters registered to help out Operation Helo, which formed a week ago after the hurricane devastated parts of the state, leaving entire communities destroyed and roads to hard-hit areas cut off.

Operation Helo’s goal is to quickly deliver essential supplies including diapers, food, water and insulin. The pilots also perform helicopter medical evacuations and search and rescue operations, according to the organization’s Facebook page and website. Formed with the help of social media and word of mouth among the pilot community, McSwain told CNN’s Omar Jimenez on Sunday.

The public seems to have responded, too. The website and social media campaigns have yielded more than a half-million dollars in donations to pay for helicopter fuel, a Facebook post says.

At least 117 people have died from Helene in North Carolina, according to a CNN tally.
