Terror plotters discussed sending a remote controlled toy car carrying a home made bomb under the gates of a Territorial Army centre in Luton, a court was told.
Zahid Iqbal, 31, and Mohammed Sharfaraz Ahmed, 25, spoke about making an improvised explosive device (IED) based upon instructions in an al Qaida manual entitled "make a bomb in the kitchen of your mom - by the al Qaida chef", Woolwich Crown Court was told.
The court was played covert recordings of the pair in which Iqbal tells Ahmed: "I was looking and drove past like the TA centre, Marsh Road. At the bottom of their gate there's quite a big gap. If you had a little toy car it drives underneath one of their vehicles or something."
