Who is the quickest bowler of them all?

Brett Lee has been very fast and so was Shaun Tait the other day, for example. Think Shoaib again, or Allan Donald, or Waqar Younis. A lot have bowled quick deliveries from time to time, but sometimes the pitch and the carry flatter to deceive. Graham Gooch, who faced pretty much everything around in the 70s, 80s and early 90s was fearful for his wellbeing only once, against the West Indian Patrick Patterson at Sabina Park. I can honestly say that I have never witnessed bowling consistently faster than that of Michael Holding and Thomson, which leads me down another avenue because of course the argument is hypothetical given the absence of data from the past.
