Cyber groomer Aabid Khan, who turned a 15-year-old schoolboy into Britain's youngest terrorist, has been jailed for 12 years.
The terror tutor had managed to recruit the teenager to a "worldwide" holy war against non-Muslims.
Khan, who was possibly plotting to attack the Queen, was a "key player" in radicalising others as well.
He had spent years building up a computer "encyclopaedia" of extremist material.
By the time he met 15-year-old schoolboy Muhammad Munshi from Dewsbury he even had a file on various members of the Royal family.
He lost little time enrolling the teenager in his "mission in life" - the destruction of Western values and the "wiping out" of all "kuffar" or non-believers.
The youngster, whose grandfather is a leading Islamic scholar, was in the middle of his GCSEs when arrested on his way home from school in 2006.
London's Blackfriars Crown Court heard he had two bags of ball-bearings, the shrapnel of choice for suicide bombers, in his pockets and notes about martyrdom under his bed.
Leading a double life of obedient pupil by day and surfer of jihadist websites at night, he also downloaded detailed instructions about making napalm, other high explosives, detonators, and grenades, and "how to kill".
The schoolboy boy then sent them to his "terrorist facilitator" Khan, and fellow cell member Sultan Muhammad, who also had a large library of terror documents on his computer.
Twice-married Khan, 23, a former fast food restaurant worker from West Yorkshire, was found guilty of three counts of possessing articles for a purpose connected with terrorism.
His cousin and "right-hand man", post office night sorter Muhammad, also 23, was convicted of three possession charges and one of making a record of information likely to be useful in terrorism. He was jailed for 10 years.
Munshi, now 18, was also found guilty of making an offence. He will be sentenced next month.
Home Secretary Jacqui Smith branded all three a "very real threat" following their convictions yesterday.
