Possible engine problem delays Concorde
The flight was briefly held up when the captain of the plane, which was already on the runway, asked for more checks.
He suspected there might have been a problem with one of the engine reheats. We always err of the side of caution, the spokesman said.
The aircraft took off normally and safely 20 minutes later than scheduled.
Concorde returned to scheduled service earlier this month after being grounded for more than a year following a crash in Paris in July 2000.
