In one, the numbers 1 through 199 were used to chronologically denote the free flights made by any of the three spaceplanes. For example, flight 1 (8 June 1959) was made by the X-15-1, flight 34 (7 March 1961) was made by the X-15-2, and flight 49 (5 April 1962) was made by the X-15-3. This convention ignores captive and aborted flights. </p><p>The other convention was an official three-part flight designation number, described in a 1960 letter by NASA flight research director <a href="/wiki/Paul_Bikle" title="Paul Bikle">Paul Bikle</a>,<sup id="cite_ref-13" class="reference"><a href="#cite_note-13"><span class="cite-bracket">[</span>c<span class="cite-bracket">]</span></a></sup> and split into three columns below. The first part, a number—1, 2 or 3—would denote the involved X-15 plane. The second part—a number, or "A", or "C"—would denote that individual X-15's chronological free flights; aborted flights were coded as "A", and scheduled captive carry test flights were coded as "C". The third part, a number, would denote the total number of times to-date that the individual X-15 had been taken aloft by a carrier, whether resulting in a free flight or not. For example, the X-15-1 was first taken aloft on scheduled captive test flight 1-C-1, next performed three aborted missions (1-A-2, 1-A-3, and 1-A-4), and then performed its first successful free flight on its fifth time taken aloft (1-1-5).<sup id="cite_ref-14" class="reference"><a href="#cite_note-14"><span class="cite-bracket">[</span>d<span class="cite-bracket">]</span></a></sup> </p><p>On 9 November 1962, flight 74 (2-31-52), the X-15-2 suffered a landing accident which damaged the craft and also injured its pilot, John McKay, who suffered crushed vertebrae and later returned to active flight status.<sup id="cite_ref-15" class="reference"><a href="#cite_note-15"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup> This presented North American with an opportunity not only to repair the plane, but to modify it—an idea which the Air Force and NASA were uninterested in while all three spaceplanes were in operational service, but agreed to once repairs were made necessary.<sup id="cite_ref-16" class="reference"><a href="#cite_note-16"><span class="cite-bracket">[</span>12<span class="cite-bracket">]</span></a></sup> The result was a new, distinct airframe known as the X-15A-2 which returned to flight in June 1964, first on a scheduled captive check-out flight (15 June, 2-C-53) and an abort (23 June, 2-A-54) before finally making its return free flight on 25 June (flight 109, 2-32-55), all piloted by Robert Rushworth. The flight numbering conventions made no distinction between the original craft and its modified iteration; it continued to be designated "2". </p><p>Neither convention accounted for which of the two NB-52 carriers took an X-15 aloft, given in a separate column below. On free flights, the NB-52A carried the X-15 aloft 93 times, while the NB-52B carried it aloft 106 times. </p> <div class="mw-heading mw-heading2"><h2 id="List_of_flights">List of flights</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=List_of_X-15_flights&action=edit&section=3" title="Edit section: List of flights"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <table class="wikitable sortable" style="text-align: center"> <caption><big>Flights of the North American X-15</big> </caption> <tbody><tr> <th colspan="2"></th> <th colspan="3"><abbr title="Official three-part flight designation number">3 Pt.

Evans does not provide carrier, Mach, velocity or altitude data for the captive and aborted flights, and these fields are therefore left blank. Jenkins (2000, Appendix 9) provides a subset of the data given by Evans, for the free flights only. In almost all cases, the two data sets match exactly. However, there are some minor discrepancies. For free flights 18, 73, 127, 128, 130, 131, 160, 190 and 191, Jenkins reports maximum velocities of 2,195, 3,716, 3,539, 3,702, 3,657, 3,260, 3,661, 3,869 and 3,617 miles per hour, respectively. Jenkins also reports maximum altitudes of 100,200 and 92,000 feet, and a maximum Mach of 4.17 for free flights 170, 176 and 184, respectively.</span> </li> <li id="cite_note-11"><span class="mw-cite-backlink"><b><a href="#cite_ref-11">^</a></b></span> <span class="reference-text">This summary table combines all captive and aborted flights into single entries, and makes no distinction between the X-15-2 and the X-15A-2.</span> </li> <li id="cite_note-13"><span class="mw-cite-backlink"><b><a href="#cite_ref-13">^</a></b></span> <span class="reference-text">See Jenkins<sup id="cite_ref-12" class="reference"><a href="#cite_note-12"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> for this letter.

The X-15A-2 was retired and never taken aloft again after setting the program's speed records on free flight 2-53-97 (or flight 188). Shortly thereafter, the X-15-3 was destroyed on its final free flight, 3-65-97 (or flight 191), killing pilot Michael Adams. The X-15-1 remained in service until 1968, performing final free flight 1-81-141 (or flight 199). However, the X-15-1 was taken aloft one last time on aborted flight 1-A-142, in one of several failed efforts to make a 200th and final free flight in the program. The sum of the final free flight numbers' second parts, 53, 65 and 81, return the 199 overall free flights of the program. The sum of the three final flights' third parts, 97, 97 and 142, return the grand total 336 flights of the program. Subtracting the former from the latter gives 137, the total aborted and captive flights.</span> </li> <li id="cite_note-17"><span class="mw-cite-backlink"><b><a href="#cite_ref-17">^</a></b></span> <span class="reference-text">This column sorts notable flights in a hierarchical ordering of attributes.

Third, the flight setting the program's Mach and speed records is listed. Fourth, each plane's first and last times aloft or in flight are listed (sequentially, then chronologically). Fifth, each pilot's first and last times aloft or in flight are listed (alphabetically, then chronologically). Finally, general comments are made in some cases.
