The pilot episode of the series, 'Encounter At Farpoint', first aired on American TV on September 28, 1987.
It took a further THREE years for the BBC to broadcast the show - I first saw it in late 1990 on Wednesdays at 6.00pm on BBC2 when I was 14 years old, but I remember it clear as day. I was completely obsessed with that show as a teenager.
^ Note the beardless Riker and the very young Wesley and, of course, Tasha Yar.
Can't believe (for me in U.K.) 22 years have passed since I saw it first.
