Since some idea of a plan is forming in my head I think it's time to ask this question: who is the copyright holder of the SWAT Kats? If we try to bring the show back it will be necessary to talk to the copyright holder eventually.
There are a few people I could ask about this question, probably the easiest to reach would be Lance Falk. I'll try asking him soon.
That's all for now.
Update: he has responded. The current holder is Warner Brothers.
