Everyone born prior to the Reagan Administration knows where they were when they heard the Challenger has exploded. It was the most tragic disaster related to space exploration the world had ever seen.

Get the Challenger mug.
(Challenger II) One of the Best Army Tanks in the world, utilised by the British armed forces. It is the size of a large garage, weighs over 60 tonnes and carries enough of an armoury to wipe out a far greater number of T55 Soviet tanks as was proved in Iraq.
I'd much rather be in a Challenger II than one of the 14 odd T55's that got destroyed

What is yelled after someone calls shotgun. When a challenge is issued the two battle in rock-paper-scissors best two out of three. Whoever wins holds the right to shotgun for the way to the destination. In order to avoid a dreaded challenge he or she has to yell "shotgun no challenge".

The British Challenger tank is the fastest and most powerful tank in the world to date. With its revolutionary fireing mechanism and armour it is able to withstand multiple RPG hits with out penertrating into the cab or turret. It has a huge 12 cylinder diesel engine in the back which produces 1200hp and is able to make it travel at over 40mph on rough ground even though it weighs over 62 tonnes. It has been used in Iraq and Afgahnistan and proven itself to be the best main battle tank in the world. It also come as standard with a kettle!!
Jeremy Clarkson stood under challenger gun - "The thing im most interested in though is the big gun, which you can see is rifled for greater accuracy. Unlike those smooth bore American ones that just hit something... over... there."
