I know what you're thinking, but no, you still can't push him out.

Anyone could have been on that plane provided they bought a ticket. The fact that nobody else was is irrelevant. The information was not only knowable to those with a fiduciary or confidentiality obligation to the company.

If you're traveling as a regular passenger, you still would not have a fiduciary relationship with Boeing and you have no confidentiality obligations regardless of who else is on the plane.

There is a chance that the plane crashing would improve Boeing's management.
