The Plane Emoji React refers to a viral phenomenon on Facebook in mid-2018 where a hidden or glitched reaction option appeared as a small airplane. Unlike the standard reactions, the plane was reportedly part of an employee test or an unintentional bug that users could briefly access by updating their app or clearing their cache. It quickly became a meta-meme where thousands of users commented specific hashtags like #AddPlane in hopes of unlocking the elusive icon. The meme represents internet FOMO (Fear Of Missing Out) and the collective obsession with secret features or Easter eggs on social media platforms. Today, it serves as a nostalgic reminder of the chaotic and harmless glitches that occasionally unify the internet.
