The executive director of the Westmoreland County Airport Authority is denying reports that plane loads of immigrants are flying into the Arnold Palmer airport in Latrobe during overnight hours. Gabe Monzo says he does not know how such rumors got started but told a meeting of the authority’s board yesterday that he has been getting called about it — including some inquiries from police. Monzo said — “It’s not happening. We have over 100 cameras on this airport. It’s not part of what we do.”
