Phonetic Alphabet ??

[Laura E. Thornsberry]

I am working on a transcript about airplanes.  In order to identify the aircraft they are speaking of, they use the phonetic alphabet.  Example:  the aircraft tail number is N9201X.  When they speak of the airplane, though, they say:  "November 9201 X-ray".  another plane:  391SR, they say:  391 Sierra Charlie.  Any thoughts on how to do it in the transcript?   Should I do "November-9201-Xray"  and "391-Sierra-Charlie"  or should I just leave it?  any help would be great!!!  OH, and frequently they just say "the 01 Xray"  so "01-Xray" and keep it all together, or "01 X-ray"

THANKS!
