UK and French certificating authorities for the Aerospatiale/ British Aerospace Concorde have said that they need more time to study safety modifications to the aircraft after they were presented with additional data on 24 August. Approval to restart services had been expected last week. Now they are reluctant to predict when they will be ready to make a recertification decision, putting into doubt the hoped-for service entry dates of late September for British Airways and late October for Air France. The aviation authorities say they have been seeking more data on possible combinations of circumstances. Air France conducted test flights at supersonic speeds with its first modified Concorde(F-BVFB) on 22, 24 and 27 August.
