...think of the many who attempted to reject a takeoff (at speed below V1 like the book says) and... were not able to stop before the end of the said runway.
BelArgUSA,
Do you have links/citations for any of the "many" above? I only ask as I've spent some time trawling the 'net for reports of overruns and all I can find are references to landing accidents & post-V1 rejects. It would be interesting to view an objective publication on a sub-V1 incident to see where it went wrong...
