A hearing in the case of two doctors charged over the suspected failed bombings in London and Glasgow has taken place at the Old Bailey.
Father-of-one Dr Mohammed Asha is a neurologist
Bilal Abdullah, 27, and Mohammed Asha, 26, are being held in custody accused of conspiracy to cause explosions.
The pair had been due to appear via video-link from Belmarsh Prison but a technical problem prevented this.
Instead, the preliminary hearing took place in their absence. They will be given a transcript of the proceedings.
The case was adjourned until 10 September, when the men are due to appear in court for a committal hearing.
Iraqi-born Dr Abdullah was arrested after a flaming Jeep was driven into the main terminal building at Glasgow Airport on 30 June.
Dr Asha, from Newcastle-under-Lyme, Staffordshire, was arrested on the M6 motorway in Cheshire later that day.
Another man, Dr Sabeel Ahmed, 26, has also been charged in connection with the inquiry and was remanded in custody at City of Westminster Magistrates' Court on 16 July.
His brother Kafeel Ahmed was detained after the Glasgow incident and remains in hospital under armed guard with 90% burns to his body.
A fourth doctor, Mohammed Haneef, 27, had been accused in Australia of providing support to a terrorist organisation, but the charges against him were dropped on Friday.
Dr Abdullah, who was the first to be charged with conspiring with others to cause explosions, was remanded in custody on 7 July.
The charge against Dr Asha accuses him of conspiring with Bilal Abdullah, Kafeel Ahmed and others unknown to cause explosions of a nature likely to endanger life or cause serious injury.
Dr Asha was remanded in custody by Westminster magistrates on 20 July.
Last month, two cars containing petrol, gas cylinders and nails were discovered in London. A day later a burning car was driven into Glasgow airport.
