FWIW,
An Eagle Saab captain was been bounced by a tug in DFW. An Emery captain was run over by a forklift and had both legs amputated.
Brown pilots are all issued a reflective vest. I think it just gives the drivers something to aim for since a couple have been tagged anyway.
Most important point in wearing the vest, what happens to your workman comp if you are injured while not wearing one when it is required by the company?
