Eight years on, it remains one of the most important away triumphs in the history of Reading Football Club.
Reading travelled to an out-of-form West Ham United, who had won just one of their last six games, on the back of ten wins in the previous twelve games which had taken Brian McDermott's men above The Hammers in the table and into the automatic promotion places.
It was Sam Allardyce's side that came out of the blocks quickest however, with skipper Kevin Nolan rattling the woodwork.
The hosts would not be denied an early lead however, with Carlton Cole finishing well beyond Adam Federici after a neat knockdown from Nolan.

As is stood, it would be West Ham finishing the day in the automatic spots, two points above Mcdermott's men.
But, after a frustrating opening half - which saw Noel Hunt have an effort cleared off the line, the game would be turned on it's head before the referee's half time whistle.
Set-piece specialist Ian Harte, who looked to be nursing an injury, curled in a delicious corner which was met powerfully in the air by centre-back Kaspars Gorkss who headed beyond former England goalkeeper Rob Green, sending the 3,000-strong travelling support into complete delirium.
The visiting contingent barely had a chance to catch their breathe in the away end before a moment of indecision from West Ham's James Tomkins ultimately gifted a chance for Noel Hunt to put Reading ahead, which Hunt gratefully accepted.
After fifteen minutes of calmness for the visiting supporters, the game resumed with West Ham pressing for a goal to get them back on level terms.
However, Noel Hunt was brought down in the West Ham area with an hour on the clock. Ian Harte stepped up and converted the spot kick - giving Reading a two goal advantage.
Ricardo Vaz-Te halved Reading's lead after he rose highest from a West Ham corner, setting up an incredibly nervy finale as Reading sought to secure the priceless three points.
With West Ham pressing, Noel Hunt and Mikele Leigetwood combined well with the latter capping off a spectacular afternoon for Brian Mcdermott's side with a fourth goal.
Two more away triumphs followed, at Brighton and memorably against Southampton before Reading ultimately secured only the second ever promotion to the top-tier of English football for Reading FC.
