Chris, I know this might not be answering the question, but I love the introductory paragraph ("I was brought up...")!
That in itself is almost good enough to open an angsty Graham Greene-style piece for me - such a good piece of writing
As for the verse itself, for me it's a mixed bag. It's a mixture of rich imagery and depth of thought (if not feeling) and something that sometimes stumbles technically.
Image-wise I think it's wonderfully evocative; a post-aviation world remembered by the obsolete technology itself. I'm a paid-up, card-carrying champion of the aerospace industry, so this strikes a chord with me. To me, it highlights how we take for granted - and in some quarters actively castigate - a capability that has transformed the world immeasurably (in a good way). In fact, the only way we might measure that transformation is by taking away the capability completely, and all that leaves behind. The flipside? Probably a slightly niche topic. Now I get the pretty strong feeling that my interpretation is not exactly what you were getting at, but that's ok - you're just fulfilling Göethe's brief to the Poet
It's almost like a parody of a protest song in places.
Another first-world airport pours
New concrete path to great outdoors;
Terminal building soars, ignores,
Destinations except profitability.
I love the first three lines, but the last line is a little cliché. For me the explicit allusion to the profitability aspect not only seems a little too obvious and at odds with the thoughtful imagery running through the rest of the piece, but also trots out a tired anti-capitalist message which is a little upper-sixth for my tastes. Sorry if that sounds harsh, but it's only my opinion, and there'll be plenty of folks to whom this line would speak a truth.
Technically, the first four lines are iambic, but the rest seems to flow as quatrains, which seems a little odd, especially as - as you say - the rhythm "hiccups" a few times. Take this passage
So no-one's planned for beasts, or crew, or handler
Barely remembered pilot, cockpit crew.
Unthought of porter, mechanic, cook or chandler
Money's a'wastin' since the big birds flew.
The first two lines are fine, but the "unthought of" really jars because it throws off the rhythm. The "thought" of "unthought" and "of" are the culprits here as they place the stress in the wrong place and make the iambic beat stumble. I couldn't think of many alternatives, but "jobless" seemed to do the trick. "Mechanic" also seems too long. I know you've got your caveats in - if was sung it'd be ok - but as a piece of poetry this stuff sticks out - sorry.
I'm really muddled over this piece - it does give me a good feeling, and ties together individuals' tales (Abdul the goatherd, the grieving mother, the local farmer - even the outliers of the industry, such as the mechanics
et al) in a skilful manner; the stories it tells are really wonderful. But because you've chosen to do this through the medium of verse, and quite complex verse, I just feel it needs a little more polish, and suffers from not being accompanied by its music, because the silence of the page shows up every slip in the rhythm.
