FYI, in post 28419 jrl767 rejected MCO for 1A, but I don't think he's explicitly rejected my PBI replacement guess yet.

Sorry, meant PBI for the end of 1A.

My OCD kicked in yesterday, as I was contemplating how to best organize this stuff. So, I offer you the following XLS. It doesn't include as much information as it could (e.g. no usernames and I couldn't figure out a graceful way to account for a/c that have been identified as correct but incorrectly placed) because I was fearful of creating too much clutter. I will probably make columns B-G a little fatter in order to accommodate multiple current guesses, so please don't be deterred from guessing based on their slimness.

In terms of color coding, current guesses are yellow, and answers confirmed correct by jrl767 are green.

I haven't uploaded it to Google Sheets yet, but will do so within in the next day or two after I sleep on it and incorporate any feedback you guys (especially jrl767 ) might have.

(1D) UA CR2 CPR-DEN to UA 727 DEN-DTW
  • 1A / 1B PBI is CORRECT (apologies to moondog for overlooking that yesterday)
  • 1B CO is CORRECT;735 is CORRECT; IAH is CORRECT
  • 1C M80 is INCORRECT but appears on another segment; CPR is INCORRECT
  • 1D UA is INCORRECT; DEN is INCORRECT; 727 is INCORRECT (note also that DEN is nowhere near the Great Circle track between CPR and DTW)
the spreadsheet is excellent

I cleaned up the structure XLS a little bit since I first posted it. Apart from optimizing column widths, I managed to squeeze in the new "A/C to be placed" column. These are airplane types that jrl767 has told us appear in the set, but we have yet to place them in the correct segments.


My only contribution in terms of new guesses for this post is throwing out the MD-80 for CLT-PBI in 1A. My rationale for this is that M80 needs to fit in somewhere in 1A, 1B, or 1D. By testing it out in 1A, if it works, we can completely close out 1A. And, if it's incorrect, our remaining a/c type choices for the empty cell in 1A will be quite limited.

I really wanted to propose another Wyoming airport, but I couldn't think of any that had service to places other than SLC (we need this for the DL or DL regional affiliate segment) and/or DEN (not allowed), let alone along the Great Circle track between central Wyoming and DTW.

1A- US M80 for CLT-PBI is INCORRECT

I’m continuing to refine the narrative for the remaining two parts of the journey

1A- 767 is INCORRECT
1B- M80 is CORRECT

Got it. I'm pleased that 1B is now closed out. I'm not making any additional guesses in this post because I'm ashamed by the volume of failed attempts at the airplane for CLT-PBI, I still don't have any good ideas for WY airports, and I figure we need to nail down the WY airport in order to intelligently attack the four cells in the bottom right. I've attached the current version of the actual XLS file I've been using to this post, so you guys can download and experiment if you wish. I think the formatting has probably reached the limits of what minor tinkering can improve, though another wrong guess for CLT-PBI (is that even possible?) would compel further adjustments.

the airport criterion is “near” (i.e., not necessarily “the nearest to”) the destination

”further adjustment” — increase row height (and use wrap text in Col J) rather than increaimg column width

Well, I figure it's obviously not Riverton, but the next closest 5 or 6 airports didn't make a great deal of sense to me either. Given your "great circle track" clue yesterday, I'm guessing some midwestern airline served one of these airports for a brief period of time. I just have no idea where to begin (i.e. I'd do even worse than tossing out random US Air plane types because at least those choices are fairly easy to identify).

How's that? This version is attached here as an XLS as well.

Thinking about this more, I'd like to guess MKE as the connection airport in 1D. If that turns out to be correct, it might be possible to reverse engineer some of the other missing links.

Let's keep throwing things and see what sticks...

1A) US 737-300 CLT-PBI
1C) DL M80 SAN-SLC connecting to a CR1 SLC-COD
1D) NW D92 COD-MSP connecting to a 72S MSP-DTW (I'm not sure whether we disqualified NW as it was guessed earlier)

you’re much closer, but still not all the way there

1A- 733 is INCORRECT
1C- M80 is INCORRECT; COD and CR1 are both INCORRECT
1D- NW and MSP are both CORRECT; the 72S is on the first leg

The introduction of NW to the mix has give me the confidence to nominate BIL (Billings, MT) to occupy the final vacant airport cells. I have included the GCM screencap below to demonstrate that this candidate checks off the "tracks great circle" requirement in spades.
