The three men deny being part of a conspiracy to launch suicide attacks
Three men plotted with the ringleader of a conspiracy to launch suicide attacks on transatlantic passenger aircraft, a court has been told.
Adam Khatib, Mohammed Shamin Uddin and Nabeel Hussain assisted Abdulla Ahmed Ali, convicted last month of conspiracy to murder, a jury has heard.
The prosecution said each of the men was "prepared to help in the commission of terrorist acts and indeed did so".
Mr Khatib denies conspiracy to murder. The other men deny terrorism offences.
Woolwich Crown Court heard that Ali was convicted in September 2009 of conspiracy to murder alongside Assad Sarwar and Tanvir Hussain and that the plot involved the "deployment of suicide bombs upon passenger aircraft".
Mr Khatib, 22, of Walthamstow, is accused of plotting with Ali, the two other convicted men and "persons unknown".
Peter Wright QC said: "He was a young man seeking to play his part in conspiring to bring about murder of innocent civilians by taking part in a plot to murder."
He added: "During 2006 Adam Khatib was involved with Mr Ali in seeking to bring about a deadly attack upon the civilian population by the detonation of improvised explosive devices."
Mr Uddin, 39, of Stoke Newington, is accused of preparing for terrorism by meeting with Ali four times in July and August 2006.
He is also accused of researching the use and purchase of hydrogen peroxide and possessing materials that could be used for terrorism.
Mr Wright described Mr Uddin as a "radicalised and committed Islamist".
The jury was told when his home was searched, material was found which, it is alleged, revealed "a state of mind in pursuit of a terrorist agenda".
Mr Hussain, 25, of Chingford, east London, is accused of preparing for terrorism by meeting Ali twice in July 2006.
He is also accused of having various items - a will, mobile phones and a £25,000 loan application for use in terrorism.
Mr Wright said: "We say such material is consistent with him fundraising for terrorist activity or contemplating taking his own life and making provision for his family."
The prosecutor said Mr Khatib's fingerprints were found on an empty packet of latex gloves in the "bomb factory" used by Ali and Tanvir Hussain.
He was also said to have visited Pakistan from where the men were being directed, the jury heard.
He added that Nabeel Hussain met Ali in Lloyd Park, Walthamstow during a "particularly busy time" in the plot.
Mr Wright said: "Why would it be that Mr Ali would have time to engage in this meeting unless... that meeting was indeed between two men who were both engaged in terrorist activity at that time."
The trial continues.
