Initially, as increases in speed were made in small steps towards possibly unknown control difficulties the horizontal stabilizer was left at its pre-launch angle set on the ground as there was concern that adjusting it at high speed would cause severe control problems. Nevertheless, in October 1947, when test pilot Yeager ran out of elevator authority (no pitch control) at Mach 0.94 it took the test team by surprise until they realized that extra control was available by moving the horizontal stabilizer.

NACA continued to fly the aircraft until January 1958, when cracks in the fuel tanks forced its grounding. The X-1B completed a total of 27 flights. A notable achievement was the installation of a system of small reaction rockets used for directional control, making the X-1B the first aircraft to fly with this sophisticated control system, later used in the <a href="/wiki/North_American_X-15" title="North American X-15">North American X-15</a>.

Flown from an <a href="/wiki/Boeing_B-50_Superfortress" title="Boeing B-50 Superfortress">EB-50A</a> (s/n #46-006), it was to be used for heat transfer research. The X-1D was equipped with a new low-pressure fuel system and a slightly increased fuel capacity. There were also some minor changes of the avionics suite. </p><p>On 24 July 1951, with Bell test pilot Jean "Skip" Ziegler at the controls, the X-1D was launched over <a href="/wiki/Rogers_Dry_Lake" title="Rogers Dry Lake">Rogers Dry Lake</a>, on what was to become the only successful flight of its career. The unpowered glide was completed after a nine-minute descent, but upon landing, the nose landing gear failed and the aircraft slid ungracefully to a stop. Repairs took several weeks to complete and a second flight was scheduled for mid-August. On 22 August 1951, the X-1D was lost in a fuel explosion during preparations for the first powered flight. The aircraft was destroyed upon impact after it was jettisoned from its EB-50A mothership.<sup id="cite_ref-X-1_fs_32-0" class="reference"><a href="#cite_note-X-1_fs-32"><span class="cite-bracket">[</span>32<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="X-1E">X-1E</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Bell_X-1&action=edit&section=12" title="Edit section: X-1E"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>(<b>Bell Model 44</b>) </p> <figure class="mw-default-size mw-halign-left" typeof="mw:File/Thumb"><a href="/wiki/File:Bell_X-1-3_being_mated_with_the_motherplane.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/1/1b/Bell_X-1-3_being_mated_with_the_motherplane.jpg/220px-Bell_X-1-3_being_mated_with_the_motherplane.jpg" decoding="async" width="220" height="165" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/1/1b/Bell_X-1-3_being_mated_with_the_motherplane.jpg/330px-Bell_X-1-3_being_mated_with_the_motherplane.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/1/1b/Bell_X-1-3_being_mated_with_the_motherplane.jpg/440px-Bell_X-1-3_being_mated_with_the_motherplane.jpg 2x" data-file-width="3000" data-file-height="2250" /></a><figcaption>Bell X-1-3, aircraft #46-064, being mated to the B-50 mothership for a captive flight test on 9 November 1951.
