This in from Notify NYC:
Tomorrow [Thursday], August 27, 2015 at approximately 10:30AM there will be a flyover involving four military aircrafts [sic] near the Statue of Liberty and Freedom Tower in Lower Manhattan. The event will consist of a B-25, P-51 [photo], F-16, and F-22. The planes will converge in New York Harbor and maintain an altitude of 1500 – 2000 feet. The aircrafts [sic] will then travel northbound along the Hudson River and land in Newburgh, NY.
The aircraft should be visible from the Promenade and from Brooklyn Bridge Park. If you hear something louder than, and different from, the usual helicopter racket Thursday morning, don’t be alarmed.
