In the section "Flight Information", the latest edition of the resume by Colonel Dan Javorsek simply refers to the YF-220 and X-273 as "prototype" and "demonstrator aircraft" respectively rather than simply YF-220 and X-273. This is very similar to how the YF-24 designation was initially listed in the initial edition of the resume by Colonel Joseph Lanni but was omitted from later editions of Lani's official resume for the sake of confidentiality, just as YF-110B and YF-113E were listed in initial editions of resumes of USAF pilots that flew captured Soviet MiGs before being omitted from later editions of those pilots' bios.

Since the existence of an NGAD demonstrator was hinted at in late 2020 and YF-xxx designations have been used as cover designations for technology demonstrators and so-called "classified prototypes", and Boeing, Lockheed Martin, and Northrop Grumman each built one NGAD technology demonstrator according to a recent podcast from the Defense & Aerospace Report, it's probable that X-273 was allocated to one of the NGAD demonstrators, in which case X-63 and X-64 might have been assigned to the other two NGAD technology demonstrators.
