To this day, thirty-three years later, Jim Hall’s zero-zero ejection test remains the only 0-0 test that was executed with a human subject in the United States by an American Company.

Many thanks to the fine folks at Convair F-106 Delta Dart for preserving and posting this information:
Project 90, A study in 0-0 Ejection
Zero-Zero – just about the lowest point in the Ejection Envelope. Sitting on the ground, with the aircraft immobile.An emergency arises and you don’t have time to hop out of the cockpit and run. What can you do? How do you know the seat will work? Will it launch you high enough for the parachute to open? Will you be injured by the force of the launch?
These questions led to a unique test. In the mid-1960s a firm that had made its name providing ejection seats and egress technology to both the military and to NASA decided that instrumented dummies did not provide all the information needed. They felt that certain questions of human physiology needed to be answered by a test of a live human. Weber Aircraft’s seats had saved over 500 lives by this time. They had been fitted to such varied craft as the F-106 and the Gemini Space capsule. The F-106 seat included the latest technologies available to allow for a clean ejection, including a gun deployed parachute, rocket motor, and self deploying survival equipment.
In late 1965, Jim Hall a professional parachute safety instructor and Major in the Air Force Reserve volunteered to act as the human guinea pig for the 0-0 seat package. He was instructed in all facets of the seat operation. He viewed films of the 43 sequential successful tests of the F-106 0-0 system. He also was measured for center of gravity in order to align the rocket exhaust with the center of mass of the man-seat package. In the tradition of the day, he visited the assembly line and selected the particular seat he would later ride. The engineers checked and verified all functions of the particular seat. They selected a lake not far from the factory for the test. A set of seat rails were attached to a test stand. The date and time were selected. And then it was time.
Jim Hall, accompanied by a platoon of engineers, arrived at the site and was shown the seat. Now it was mounted on the rails, wired and ready to fire. Every mechanical function had been checked and double checked. Major Hall was attired in an orange flight suit. Its arms were cut away at the shoulder to reveal a small area of skin that had been marked by pigment. He was strapped into his chute and assisted into the seat. All the straps were connected and tightened. The engineering cameras were armed to record every aspect of the test, even the slump of Jim’s shoulder markings under launch acceleration. Then the engineers withdrew to a safe distance. The rescue launches on the lake were signaled, and the countdown began… Major Hall gripped the handles built into the sides of the seat bucket and pulled them up to the firing position… and nothing happened… for one long second. The delay cartridge allowed the high speed cameras to get to speed and then the hot gas was unleashed into the catapult initiator. The Major rose up the rails with anonset rate of 150 g’s/second with a maximum of about 14g’s. The rocket ignited as the seat cleared the rail providing the huge jet of flame in the above picture. One second and almost 400 feet later, seat separation occurred. The parachute gun fired, and two seconds later the parachute was fully inflated. The survival kit automatically released and dropped to the end of its lanyard. The rubber raft, suspended from the same lanyard, immediately inflated.
Approximately 26 seconds after Major Hall pulled the handles he landed in the lake.A journey of only a few dozen yards had taken him to an altitude of about 400 feet andinto the history books (albeit only a few obscure ones…).
To this day, thirty-three years later, Jim Hall’s zero-zero ejection test remains the only 0-0 test that was executedwith a human subject in the United States by an American Company. (The first known live 0-0 test was executed in 1961 by Martin-Baker Aircraft Co. Inc.. Doddy Hay, a M-B employee, was the ‘Man in the Hot Seat’ for that first test. There have been several other live tests, most of which have been at altitude, or with some airspeed.)

General Jim Hall and his parachute – a bit
more advanced than Andre-Jacques Garnerin’s!
Yesterday a Google Doodle commemorated the first parachute jump 216 years ago by Andre-Jacques Garnerin.
This is a great opportunity to give a nod to pioneers in parachuting and also to expand the general public’s knowledge of this historic event in 1797.
As you probably know, Google Doodles are created to celebrate some important event or for the celebration of an achievement. The doodles which are often interactive add an element of fun and thrill to the otherwise colorfully static Google logo.
In an article in the India Times technology column, Andre-Jacques Garnerin is given credit for inventing the frameless parachute. He deployed his umbrella-shaped prototype, which was 7 meters across, at Parc Monceau, in Paris, France on October 22, 1797. Read more about it HERE; hope you enjoy the interesting details in this write-up. Don’t let the visuals of a parachute with an attached basket fool you! This is all about parachuting.
If you happened to miss the Google Doodle yesterday, you can see it in full motion, color and sound HERE on YouTube.

Excitement continues to grow for the Pioneers of Parachuting SkyDivers Reunion in Orange, Ms in Sept. Only recently did I learn that Orange has a section called Jumptown. That should be interesting!
Had lunch recently with Vern Williams and Bud Kiesow, pioneers from early Calif. days. Lots of memories and laughs. Bud still lives in Calif.; Vern lives in Colorado. We went to SkyVenture Colorado and met up with Kim Emmons Knor, enjoyed watching jumpers practice in the tunnel! Jim and Kim will see you in Jumptown!

Ace was a Wonder Dog late in her life. She had been abused by the local kids as well as adults in fights. She needed someone who would care for her in a tough kind of way. Jim Hall’s way. Ace had been a victim of bullying though we didn’t call it that back then.
