<p class="MsoNormal">Authors,</p>
<p class="MsoNormal">I thought that I had years ago declared that a speed of 999 would mean Orbital Velocity 17,500 MPH and that 998 would mean something else for high speed jets. Maybe mach 3?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Actually I may have defined three speeds greater than 999 for the last three enetries.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Clearly we need orbital velocity for the Space station, etc…</p>
<p class="MsoNormal">And Mach 3 for our fighter pilots…</p>
<p class="MsoNormal">And something for the Concord (or its replacement)…</p>
<p class="MsoNormal">What about Elon Musk’s hypter tube? But I think it is under 999…</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Anyway, is this written down anywhere?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">And if not, then here is what I propose:</p>
<p class="MsoNormal">999 = 17500 MPH space station</p>
<p class="MsoNormal">998 = 1850 MPH military</p>
<p class="MsoNormal">997 = 1350 MPH concord</p>
<p class="MsoNormal">996 = 996 MPH</p>
