Two different plans burst into flames last weekend in the US, as a result of unforeseen technical issues.

One of them, a FedEx plane, caught fire just after landing in Fort Lauderdale International Airport in Florida, when the plane's landing gear failed. The plane crashed and sparks started flying, causing a fire, which the crew soon managed to put out.

The pilot and co-pilot, who were the plane's sole occupants, escaped unharmed.

FedEx has announced the company will cooperate with the authorities.

Two hours earlier, a fire broke out just before takeoff on an American Airlines plane carrying 161 passengers and crew. The plane had been scheduled to fly from Chicago O'Hare International Airport to Miami.

The American National Safety Council has investigated the two incidents and says there is no connection between them.
