presuming we are still taking bids/bets on the jets that served the state capitols, herewith a few guesses:
- Harrisburg (MDT) - Allegheny DC-9-30
- Salem (SLE) - United 737, possibly Air West DC-9-10
- Lincoln (LNK) - United 737, Frontier 737
I also believe Jefferson City was actually served through Columbia even though it has its own airport - COU probably saw Ozark DC-9-10/30
