Naming scheme exception

The claim in the head section that it is the "only Boeing-designed production jetliner that does not follow the 7x7 naming scheme" has no citations. A version of the claim was originally added anonymously in https://en.wikipedia.org/w/index.php?title=Boeing_720&oldid=828761388

I was able to find some (perhaps unreliable) secondary sources that made similar, but not identical, assertions, to the current one, usually with the a caveat similar to "to this date".

This seems like original research and trivia that does not belong in the head section.

It was added here without explanation. Some naming text is in the body but none supports this claim, entry removed. Nimbus (Cumulus nimbus floats by) 08:47, 22 April 2024 (UTC)[reply]

Boeing 720-023B as a variant?

The Boeing 720-023B should be considered one of the variants despite only having one aircraft produced Sizzlepop1 (talk) 13:59, 10 May 2024 (UTC)[reply]

The 023 is the customer code for American Airlines, the original operator. There were 25 720-023B, 10 converted from the base variant and 15 delivered new. The aircraft I believe is being discussed is the Pratt & Whitney engine test bed C-FETB (ex-American Airlines N7538A). Its modifications would have been approved through a supplemental type certificate (STC). Nimbus (Cumulus nimbus floats by) 14:28, 10 May 2024 (UTC)[reply]
