I poked around and this is running off a GraphQL endpoint at https://api.epstein.flights/ - I pointed the GraphiQL desktop app at it and the following query returned some interesting data:

    {
      passengers {
        pageInfo {
          count
        }
        edges {
          __typename
          ... on VerifiedPassenger {
            id
            slug
            name
            biography
            wikipedia_link
            flightCount
            image
            histogram {
              month
              count
            }
          }
          ... on LiteralPassenger {
            literal
          }
        }
      }
    }
