Three men have been convicted of plotting to blow up airliners using home-made liquid bombs. Find out more about the background to the case with the slideshow below.
Airline terror plot: The evidence
Abdulla Ahmed Ali, Tanvir Hussain and Assad Sarwar were arrested in August 2006. They were each accused of two charges of conspiracy to murder using home-made explosives.
All three were found guilty in an earlier trial of conspiracy to murder involving liquid bombs - but that jury could not decide whether their plans extended to detonating the devices on planes.
Now a second jury has decided that such a terror plot did exist.
The prosecution alleged that the three ringleaders planned to explode home-made bombs disguised as soft drinks on seven trans-Atlantic flights from London's Heathrow airport.

3. 1515 AC865 LHR-MONTREAL (Air Canada)
4. 1540 UA959 LHR-CHICAGO (United Airlines)
5. 1620 UA925 LHR-WASHINGTON (United Airlines)
6. 1635 AA131 LHR-NEW YORK (American Airlines)
7. 1650 AA91 LHR-CHICAGO (American Airlines)
During their investigation police found equipment that could have been used to make bombs in King's Wood, High Wycombe, and in Forest Road, east London. Assad Sarwar, the quartermaster, bought a suitcase to store bomb parts in the woods near to his home. There, he hid bottles of hydrogen peroxide, also known as hair bleach. This chemical was the key ingredient for the home-made bombs.
At the bomb factory in east London, the ringleaders experimented with the design of their devices which were to be disguised as soft drink bottles. The small bombs would then be smuggled in hand luggage through airport security.
The theory of bomb construction is detailed above, but precise details shown to jurors have been omitted.
