COMMENTS

"Alpha" and "Juliet" are sometimes spelled "Alfa" and "Juliett" to clarify pronunciation for non-English speakers. Also, "Xray" is usually spelled "X-ray", which makes 5 characters. - M. F. Hasler, Jul 24 2012

The Google alphabet described in the Ouzan link is a function of the date and the country, but is nevertheless an interesting footnote to this sequence. - N. J. A. Sloane, Mar 01 2015
