Mystery Aircraft Triggers Questions Off Tulum Coast

Tulum, Quintana Roo — An aircraft conducting multiple passes off the coast of Tulum has drawn the attention of flight tracking enthusiasts due to its unusual flight patterns and lack of clear identifying information.

According to data from tracking applications, the plane appeared with the call sign ANX3531, originating in Albuquerque, New Mexico, with no destination listed. The available records showed irregularities including a registration marked as “00000000,” an unknown aircraft type, and an alert for a possible transponder malfunction.

The tracks recorded over the Caribbean Sea and the Quintana Roo coastline match patterns that could correspond to technical flights, calibration missions, data collection, cartography, or environmental monitoring. However, there is no public evidence confirming whether the flight was an intelligence operation or any irregular activity.

The lack of official information has fueled speculation among aviation monitoring enthusiasts, though experts in flight tracking caution that flight routes alone do not reveal an aircraft’s purpose.

Neither Mexican nor U.S. authorities have issued any statements regarding the flight recorded off Tulum. The aircraft remains under observation by flight tracking hobbyists as its specific function remains unexplained.
