A Delta Air Lines pilot received a warning about a possible rocket launcher attack while approaching New York's LaGuardia Airport, but the threat was quickly dismissed as not credible, police said. The alert came from an anonymous phone tip called in to authorities. Port Authority police investigated and determined within a minute that the threat was unfounded. The flight landed safely without any incident. LaGuardia Airport is one of the busiest in the United States, serving millions of passengers each year. Security officials regularly handle such threats, which are often hoaxes. The identity of the caller and the specific details of the tip have not been disclosed. Delta Air Lines did not immediately comment on the incident. The rapid response by law enforcement underscores the strict security measures in place at major airports. Passengers on the flight were unaware of the alleged threat and continued their journeys normally. Authorities remind the public that any security concerns should be reported immediately, but false alarms can disrupt operations. The incident remains under review.
