The 4th British Airways Concorde to completed the return to service modifications has competed a second key air-test that should see the aircraft return to passenger service in the next few days.
As G-BOAD had not flown since June 8th 2000, before taking part in the previous air-test at the end of January, is was felt that a second air-test would be required to fully check and re-certify the aircraft's systems before passenger flights could commence.
British Airways have been running the daily New York services with Concordes G-BOAE, G-BOAF and G-BOAG since early November and adding the 4th aircraft will take some pressure off the fleet allowing some flexibility on what aircraft are available. It has always been BA's policy to have a standby aircraft for the BA001 and having G-BOAD serviceable will ensure that it is always possible to make this guarantee to passengers in the coming months.
