Passengers onboard a British Airways flight were forced to evacuate the plane when the cabin allegedly filled with smoke.

The flight, which originated from London's Heathrow Airport, suffered from an unknown issue as it neared its destination, Valencia Airport in Spain. While the plane landed safely, passengers and crew members used the evacuation slide to exit the vehicle.

Footage that claims to show the inside of the cabin was uploaded to social media. Miguel J Galindo shared video that his daughter reportedly recorded. According to his posts, his daughter claims that the plane flew for about 10 minutes with the cabin full of smoke. She said that oxygen masks didn’t deploy during the incident.

Galindo also complained in another tweet that no info was being provided to the passengers.
