LISBON, Aug 11 (AFP) - A flight to Frankfurt operated by the German airline Lufthansa returned to Lisbon Wednesday 30 minutes after take-off when a warning light came on, an airport official said.
"As a precaution the captain decided to turn back to Lisbon, but nothing happened," Carlos Silva told the Portuguese news agency Lusa.
The plane, which had taken off at 12:41 pm (1141 GMT) was still on the ground in the early afternoon.
