Newark Liberty International Airport briefly shut down Wednesday evening due to a reported “aircraft emergency” — effectively grounding all flights for about an hour. The major airport issued a travel advisory, writing in a statement on X that all flight operations were “temporarily suspended while an aircraft is removed from the taxiway due to an earlier incident.” A ground stop was originally in place from 5:42 p.m. to 7 p.m. for an “aircraft emergency” that appeared to be caused by an engine failure on the JetBlue flight, which was headed for West Palm Beach, Florida. The plane was taking off from Newark Airport, but turned around and landed back on the tarmac just 40 minutes into the journey, according to FlightAware.
