I don't have time to sort this out, but I can advise on how to figure it out. Richmond to W-S flight inbound.

The N-number (tail number) registration has been hidden. FAA N-Number registration search
here.
From the above N-Number results, you can find the serial number ("42"). By searching the FAA database by serial number, you get a list of 94 results. Someone should go through these (especially one of you who is more familiar with names of potential boosters/donors) to see if anything pops up.

This flight looks really interesting. This is the kind of thing you'd expect from a larger university with more resources - a plane with a hidden tail number between a potential coach's hometown and the school.
