On Wednesday afternoon, many New Yorkers were surprised to see pro-Turkey and Armenian genocide denial propaganda written in the sky over the Hudson River. The skywriting featured messages such as "101 years of Geno-lie," "Gr8 ally = Turkey," "BFF = Russia + Armenia," and "FactCheckArmenia.com." The aerial stunt was part of a campaign by the website Fact Check Armenia, which denies that the genocide of Armenians by the Ottoman Empire took place, contrary to the consensus of historians.

The organization also captured headlines this week for a full-page ad placed in the Wall Street Journal, also pointing to the website. Two weeks ago, a billboard featuring a version of the same ad near Boston's Armenian Heritage Park was removed by Clear Channel after outrage from Armenians in the city.

Wednesday's messages in New York City's skies were produced by a unique form of skywriting called "sky typing" in which five planes fly in close formation to write massive letters at high altitude to produce messages over five miles long in the air, making them visible in a 15-mile (24 km) radius. New Yorkers from Brooklyn, Queens, and Manhattan could all see the messages, as documented in numerous photographs on Twitter.

The company responsible for writing the messages is the GEICO Skytypers, an air show team that performs up and down the east coast and is sponsored by GEICO, an insurance company owned by Berkshire Hathaway, the holding company for Warren Buffett, the world's third-richest man.
