A Boeing 767 traveling from Newark, N.J., was forced to make an emergency landing in Warsaw Tuesday, after the jet's landing gear failed to open.
    
Fire department officials sprayed special fire retardant foam on the runway in preparation for the landing.

The pilot circled the airport for an hour before landing to empty the fuel tanks.

Finally, the Polish LOT airlines plane touched down, skidding across the runway on its belly and producing smoke and fire.
    
All 231 people on board escaped without injury. 

"There was no panic among the passengers. The cabin crew prepared them for the emergency landing well," LOT airlines president Marcin Pirog told reporters.
    
Airline officials are congratulating the crew for a perfectly executed emergency landing.
