Looking back, I should have used my Loewy livery on the Boeing 2707-300

It's a system that is expanding the reach of electricfied transit without needing the full size batteries common on battery only electric buses thanks to under-wire charging. It still exists because the population served fights tooth and nail every time the possiblity of retiring it is proposed.

Well, this aught to be different.

It's both not inflatable, and not a Russian proposal. ntrs.nasa.gov/citations/19...

It really feels like the type of review done to show how limited the concept is, even relative to the CTV on Altas (although most of the document looks at Titan & Ariane V).

ntrs.nasa.gov/citations/19... PDF pg 100. The functionality would be similar to HTV's unpressurized section but with a lower payload. The impression I have is that it was included as an alternative for not developing a cargo transfer tug for Ariane/Titan (later ATV), with limited utility.

The concept is mostly referenced in post-Challenger liquid booster studies as a marginal abort mode to show the relative safety improvements that shuttle liquid boosters offered in multiple-engine-out abort conditions.

The paper that outlines the concept is "SPACE SHUTTLE GUIDANCE FOR MULTIPLE MAIN ENGINE FAILURES DURING FIRST STAGE" doi: 10.2514/6.1987-2398 by Steven J. Sponaugle & Stanley T. Fernandes at McDonnell Douglas.

Such views help show why there was ablator on the aft LH2 dome of the ET.

So, that document has citations back to the 2008 ACI and Weitze Research report, which I had already reviewed and is the one that I am pretty sure is the primary source of all of the errors for what 096 and 097 were, including calling them STAs. I do thank you for your effort.

Fewer stops are fewer failure points, and less time needing to be built into the schedule for margins at each stop.
