My apologies to Mr Sumwalt; I admit I scanned the bios quite quickly.
My statement was based on knowing the background of some of the others on the board, having noted their various comments during the Pinnacle/Jefferson City board meeting ... the quality of which didn't seem particularly dependent upon their specific background.
In addition, I think it's quite important that the board be seen not to be a creature of the industry; it is, after all, one of the mechanisms by which the general public assures themselves of the safety of the transportation system, and if it were staffed entirely by industry insiders, there'd be even more people willing to cry "conspiracy" at every turn. It does, after all, fulfill a quasi-judicial/legal role, and we don't apply any expertise qualification to a jury on a capital trial....
