The flight crew of a Czech Airlines Airbus A320 jet declared an in-flight emergency while en route from Paris, France to Prague, the Czech Republic.

The incident occurred on May 20, 2021, when the Czech Airlines Airbus A320-200 aircraft, registered as OK-HEU, was flying its regular scheduled flight OK761 from Paris Charles de Gaulle (CDG) to Vaclav Havel Airport Prague (PRG). According to the Radarbox.com data, the jet took off from CDG airport at 2.53 p.m. and was supposed to reach its destination at PRG airport at 4.15 p.m. 

However, when the aircraft was heading to Luxembourg, the flight crew declared an emergency by squawking an emergency code of 7700 and made a turn in a circle. Reportedly, the flight crew considered returning to CDG airport, but a few moments later, the jet continued flying towards its initial destination.

The flight tracker showed that the jet successfully landed at 4.19 p.m. at PRG Airport.
