Howell of the U.S. Air Force was strapped into the back seat of a specially-instrumented Convair F-106B Delta Dart. The aircraft climbed to 23,336 feet and accelerated to 497 miles per hour \u2014 Mach 0.76 at that altitude. At that point, on his own command, TSgt Howell pulled the handle, was ejected explosively out of the canopy by a clamshell escape capsule, deployed his parachute, and parachuted safely back to the desert floor.<\/p>\r\n\r\n<p>It was the first live human test of the Convair B-seat \u2014 the supersonic-capable encapsulated ejection system developed for the F-106 fleet.

The first-generation ejection seats developed in the late 1940s assumed subsonic ejection at relatively low altitude. They were largely effective in the 250-450 knot envelope. Above that, the dynamic pressure on the pilot\u2019s body during the ejection sequence could break limbs, dislocate shoulders, snap necks, and tear the helmet and parachute riser away from the body before the canopy ever inflated.<\/p>\r\n\r\n<p>The U.S. Air Force began losing pilots to high-speed ejection in the F-100, F-101, F-104, and early F-105 fleets. By 1955, the Air Force Flight Test Center at Edwards had documented enough cases to conclude that a fundamentally different approach was needed for aircraft routinely operating above Mach 1. In October 1957, the U.S. Air Force issued a formal requirement for a supersonic crew-escape system. The Industry Crew Escape System Committee (ICESC) was formed in response. Convair, building the F-106 Delta Dart for the Air Defense Command interceptor role, took the lead on the design.<\/p>\r\n\r\n\r\n<figure class=\"wp-block-image size-large\" style=\"margin:0 0 24px\"><img data-opt-id=2007091605  fetchpriority=\"high\" decoding=\"async\" src=\"https:\/\/ml5psubhxdln.i.optimole.com\/cb:0e0_.b970\/w:auto\/h:auto\/q:mauto\/ig:avif\/https:\/\/migflug.com\/jetflights\/wp-content\/uploads\/sites\/4\/2026\/05\/r7-convair-f-106-delta-dart-scaled.jpg\" alt=\"Convair F-106 Delta Dart\" style=\"max-width:100%;height:auto;border-radius:6px\"><figcaption style=\"font-size:13px;color:#777;text-align:center;margin-top:6px;font-style:italic\">A Convair F-106 Delta Dart of the U.S. Air Force Air Defense Command. The F-106 fleet was the first operational aircraft to receive the supersonic-capable &#8220;B-seat&#8221; encapsulated ejection system. (Wikimedia Commons)<\/figcaption><\/figure>\r\n\r\n\r\n<h2 style=\"padding-top:22px\">The B-seat concept<\/h2>\r\n\r\n<p>The Convair B-seat was not really a seat in the conventional sense. It was a clamshell capsule that enclosed the pilot\u2019s upper body and arms before being ejected from the airframe. The capsule was designed to protect the pilot from the windblast that a conventional open ejection seat could not avoid at high speeds. Once clear of the aircraft, the capsule opened, the seat itself separated from the pilot, and the pilot\u2019s personal parachute deployed in the normal way.<\/p>\r\n\r\n<p>The engineering challenge was extraordinary. The capsule had to fit inside the existing F-106 cockpit without major redesign. It had to deploy explosively in milliseconds without injuring the pilot. The internal mechanism had to release the pilot reliably whether the ejection was at 250 knots and 1,000 feet or at Mach 2 and 50,000 feet. Convair and Stanley Aviation (a major postwar ejection-seat innovator, the company behind several other USAF escape systems) spent four years on the design before they were willing to put a human inside one.<\/p>\r\n\r\n<h2 style=\"padding-top:22px\">Why Howell volunteered<\/h2>\r\n\r\n<p>The choice of a Technical Sergeant \u2014 rather than a commissioned officer test pilot \u2014 for the live-ejection test was deliberate. The Air Force\u2019s policy in the late 1950s and early 1960s was that volunteer enlisted aircrew, with extensive ejection training, were preferable for the first live tests of new escape systems. The reasoning was twofold: enlisted volunteers had broader training in the maintenance and rigging of ejection equipment (so they understood exactly what they were testing), and they could be selected from a much larger pool than the very small cadre of jet-rated officer test pilots.<\/p>\r\n\r\n<p>Howell was a parachute rigger with hundreds of jumps to his credit, extensive familiarity with the B-seat through preflight inspections at the Convair factory, and \u2014 by every account from contemporaries \u2014 exceptional physical conditioning and emotional steadiness. He spent months training on the rocket-sled mockup at Holloman AFB. He understood the system better than almost anyone else who was not an engineer.<\/p>\r\n\r\n<p>The actual ejection went exactly as the engineers had predicted. The clamshell closed. The capsule fired clear of the F-106B with the expected acceleration profile. The capsule decelerated through transonic into subsonic. The capsule opened. The pilot\u2019s personal parachute deployed. Howell landed in the desert and was picked up by the recovery helicopter within minutes. His only complaint, according to the post-mission debrief, was that the seat was uncomfortable on the way up.<\/p>\r\n\r\n\r\n<div style=\"background:#f8f9fa;border-left:4px solid #1565c0;padding:20px 22px;margin:18px 0 24px;border-radius:0 8px 8px 0;font-size:16px;line-height:1.7;display:flex;gap:20px;align-items:flex-start\"><a href=\"null\" target=\"_blank\" style=\"flex-shrink:0\"><img decoding=\"async\" src=\"null\" alt=\"Technical Sergeant James A.

Howell<\/strong> &mdash; B-seat live ejection volunteer, USAF (post-mission debrief, 6 June 1961)<\/div><\/div><\/div>\r\n\r\n\r\n<h2 style=\"padding-top:22px\">What the B-seat made possible<\/h2>\r\n\r\n<p>The successful Howell test cleared the B-seat for fleet deployment. The entire F-106 inventory \u2014 about 300 aircraft active at the time \u2014 was retrofitted over the following years. The B-seat became standard issue for the F-106A single-seat and F-106B two-seat interceptors that ringed North America during the worst years of the Strategic Air Command vs Long Range Aviation standoff. Several F-106 pilots subsequently ejected operationally in real engine failures or in-flight emergencies. While the B-seat saved a number of lives, it also suffered several fatal failures \u2014 the complicated ejection sequence proved unreliable, and the seat was replaced fleet-wide in 1964 by a simpler Weber rocket-powered seat.<\/p>\r\n\r\n<p>More importantly, the B-seat established the technical and procedural template for the next generation of supersonic escape systems. The General Dynamics F-111 Aardvark used a fully encapsulated crew module \u2014 a more elaborate version of the same idea, in which the entire two-seat cockpit detached and parachuted to safety as one unit. The B-1B Lancer used a similar concept until the B-1B fleet was modified in the 1980s to use conventional ejection seats. The Rockwell B-1A prototypes had encapsulated crew modules during their flight test programme.<\/p>\r\n\r\n\r\n<figure class=\"wp-block-image size-large\" style=\"margin:0 0 24px\"><img data-opt-id=824713158  fetchpriority=\"high\" decoding=\"async\" src=\"https:\/\/ml5psubhxdln.i.optimole.com\/cb:0e0_.b970\/w:auto\/h:auto\/q:mauto\/ig:avif\/https:\/\/migflug.com\/jetflights\/wp-content\/uploads\/sites\/4\/2026\/05\/r7-ejection-seat-scaled.jpg\" alt=\"Modern ejection seat\" style=\"max-width:100%;height:auto;border-radius:6px\"><figcaption style=\"font-size:13px;color:#777;text-align:center;margin-top:6px;font-style:italic\">A modern aircraft ejection seat \u2014 the F-106 B-seat capsule concept was eventually replaced by improved open-seat designs like the Martin-Baker series, but the engineering lessons from the supersonic test programmes of the 1950s and 60s still inform current designs. (Wikimedia Commons)<\/figcaption><\/figure>\r\n\r\n\r\n<h2 style=\"padding-top:22px\">Why it did not become the standard<\/h2>\r\n\r\n<p>The encapsulated ejection capsule concept was eventually overtaken by improved open-seat designs. Several factors pushed the industry away from clamshells. Capsules were heavy, complex, and expensive. They took up cockpit volume that designers wanted for other purposes. Most importantly, the next generation of open ejection seats \u2014 Martin-Baker\u2019s Mk 5, Mk 7, and Mk 10 series, and the ACES II series that became standard across the F-15, F-16, F-22, and F-35 fleets \u2014 were able to handle supersonic ejection envelopes through faster sequencing, better arm-restraint systems, and improved windblast protection on the seat itself.<\/p>\r\n\r\n<p>The Convair B-seat sits in the history books as the proof that the problem could be solved. The fact that it was solved differently in subsequent generations does not diminish the achievement. Without the B-seat, the F-106 fleet would have spent twenty years at the front line of North American air defence with crew survivability at the upper end of its performance envelope no better than the F-100\u2019s. With the B-seat \u2014 and the live human test that TSgt James A. Howell volunteered for at the age of thirty-one \u2014 every F-106 pilot who pulled the handle for real over the next two decades came home.<\/p>\r\n\r\n\r\n<div style=\"margin:24px 0\"><div style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;border-radius:8px\"><iframe src=\"https:\/\/www.youtube.com\/embed\/98cXGBY7qQU\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0\" allowfullscreen><\/iframe><\/div><p style=\"font-size:13px;color:#777;text-align:center;margin-top:6px;font-style:italic\">Watch: archive footage of supersonic ejection seat testing from the era, including the experiments that led to the operational F-106 B-seat.<\/p><\/div>\r\n\r\n\r\n<p><em>Sources: F-106 Delta Dart Veterans Association; Air Force Flight Test Center historical archives; Convair company records; The Ejection Site (ejectionsite.com).<\/em><\/p>\r\n\r\n<div style=\"background:#f0f4ff;border-left:4px solid #5C91FF;padding:16px 20px;margin:32px 0 8px;border-radius:0 8px 8px 0\"><p style=\"margin:0 0 8px;font-weight:600;color:#333\">Related Posts<\/p><p style=\"margin:4px 0\"><a href=\"https:\/\/migflug.com\/jetflights\/how-ejection-seats-save-lives-at-air-shows\">How Ejection Seats Save Lives at Air Shows<\/a><\/p><p style=\"margin:4px 0\"><a href=\"https:\/\/migflug.com\/jetflights\/bell-x-2-mach-3-mel-apt-inertia-coupling-1956\">Bell X-2: First to Mach 3 \u2014 and It Killed Its Pilot<\/a><\/p><\/div>\r\n","protected":false},"excerpt":{"rendered":"<p>On 6 June 1961, TSgt James Howell volunteered to be ejected at 497 mph from an F-106B Delta Dart to test the Convair supersonic B-seat capsule.
