[ale] From DSL to Fiber

[Jeff Lightner]

You're implying an airplanes doesn't ever accelerate (or even decelerate) when it "flies"?

Sorry but I have to disagree having been on many a flight in my life.  

The original question was "how long will it take to reach the speed of light" which certainly implied acceleration was occurring.  

As my nieces used to say:  So there!  :p

Errr. I'm not so sure about that. There is redundant  
information in "an aircraft flies". Now if the statement  
read "an aircraft accelerates..." I might buy the argument,  
but flying (to me at least, and I suspect in general) would  
rather imply essentially steady flight with just sufficient  
various accelerations necessary for stable flight.

Of course, being of the nature of a thought problem, the  
physics of flight (such as air resistance) can be ignored.
