The 1962-63 season stands out like a beacon in Leyton Orient's history as their one and only campaign among the elite of English football.

Johnny Carey took Orient to the top flight by steering them into second place in Division Two, only for them to fall straight back down the following season.

The 1970s were also good times for the Brisbane Road side, as they spent all of it in the Second Division and, under Jimmy Bloomfield, reached the FA Cup semi-finals in 1978 for the first and only time in their history, after shocking First Division trio Norwich, Chelsea and Middlesbrough on the way. However, Arsenal proved too strong in the last four, winning 3-0.

However, in 1982 Orient dropped into Division Three and three years later they fell into Division Four, their first time in English football's basement.

Leyton Orient spent four seasons there until Frank Clark lifted them out in 1989 via the play-offs, beating Wrexham 2-1 on aggregate.

Orient returned to the bottom league at the end of the 1994-95 season after suffering 32 League defeats and they remained there until 2006, after enduring play-off final defeats in 1999 and 2001.

Meanwhile, sports promoter Barry Hearn stepped in to rescue the club after at one point the Professional Footballers' Association had to pay the players' wages.

However, Martin Ling's appointment as manager brought renewed hope and he led them out of what was now League Two by guiding Orient to third place and automatic promotion, and they have remained there since.

Leyton Orient's roots go back to 1881, when members of an east London cricket club set up a football team to keep themselves fit in the winter. The club became known as Orient in 1888 as one of the players worked for the Orient Shipping Line.
