<P> When it opened on 28 May 1994 , Big One was both the tallest and steepest roller coaster in the world . It was also one of the longest out - and - back roller coasters , measuring 5,497 feet ( 1,675 m ) . With a 205 - foot drop and 74 mph top speed , it was second only to Steel Phantom at Kennywood in West Mifflin , Pennsylvania in speed , but it was the fastest coaster in Europe . The Big One lost its height record to Fujiyama in Japan in 1996 , though it remained the tallest and fastest roller coaster in Europe until 2002 , when Silver Star opened at Europa - Park in Germany . The ride still remains the tallest in the United Kingdom , although Stealth in Thorpe Park is the fastest . It is also the second longest in the UK , losing only to Lightwater Valley 's Ultimate . </P>
