Felix Baumgartner , working with his Red Bull Stratos team, jumped from a stratospheric helium balloon on 14 October 2012, breaking previous records set by Joe Kittinger in 1060 with Project Excelsior III. With the success of the Red Bull Stratos project, Felix set the altitude record for a manned balloon flight, parachute jump from the highest altitude, and greatest free fall velocity. Note: “Manned Balloon Flight” altitude record not ratified by FAI since that would require the pilot to land with the balloon. Left: Joe Kittinger jump with Project Excelsior III from 102,800 feet. Right: Felix Baumgartner with Red Bull Stratos jump from 128,100 feet. From AVWeb: BRANSON LEVERAGES BAUMGARTNER'S RECORD JUMP The ever adventurous and publicity-savvy Sir Richard Branson Thursday recognized Felix Baumgartner's Red Bull-sponsored record freefall by also telling the world his company once considered a jump from 400,000 feet -- and might consider it, again. In a blog post at Virgin.com Branson says his people were approached in 2005 by an individual who wanted to use SpaceShipOne for such a jump. The craft would carry the jumper to its apogee at 400,000 feet where the parachutist, clad in a fully pressurized space- suit, would simply exit. The jumper would return via freefall and parachute. Meanwhile, a pilot (also wearing a spacesuit) would remain with the craft and its life support systems to guide their safe return. Branson says the trip "is theoretically possible" but the attempt was preempted by other factors. At the time in 2005 when Branson's team was approached, SpaceShipOne was being removed from test- ing and placed at the Smithsonian Institution National Air and Space Museum. But, says Branson, tech- nology marches forward every day and "we look forward to taking on new challenges as we move closer towards commercial space flight." He goes on to suggest that "the next record leap could one day be from Virgin Galactic's SpaceShipTwo." In keeping with his reputation for adventure, Branson signs off by saying, "Haven't had a challenge myself for a while. Could be fun for Virgin to give Red Bull a run for their money." Baumgartner's 128,000-foot plunge on October 14, 2012, broke at least two records that stood for more than 50 years. He set the new mark for highest-ever parachute jump and highest manned balloon flight. He is also believed to have reached 1.24 Mach during freefall. © Pacific Coast Aeronauts, November 2012 Page 2 Downwind Chase Chico Air Show David Wakefield I’d done tethered events at air shows before, but never in Chico. The organizers were a little skeptical about what I could do there and had no experience with hot air balloons. I actually worked with the event Performer Organizer, tower staff, Air Boss and the FAA for several months to get everybody on the same page. I tried to get a number of media outlets to come out (it’s my job) but alas, they didn’t return my calls. Bummer. We (me, and crew members Laurie Pownall and Jamie Hustler) headed up early on Friday to pre- set the RE/MAX Tent and for the Friday Pilot briefing. We were met by the broker and agents from RE/MAX of Paradise and went to work, getting the tent inflated just in time for me to run to briefing. There’s something cool about being in a briefing with F-18 pilots and professional aerobatics pilots. Cool. Called the media again… same response (none). Again…Bummer. Friday afternoon also featured the first performances with performers pushing the edges of the box to entertain the people from town and let them see what’s coming for the weekend. We watched while attending a great hanger party with many of the performers stopping in. One YAK pilot taxied through at a very speedy clip making the party goers respect the road. YIKES. The performances were capped by a twilight performance by the Canadian CF-18. WOW!! Seeing an F-18 perform after dark is a very special experience. First thing Saturday morning we were there to reinflate the RE/MAX Tent and get set up for our tethered rides. We were blessed to have Jim (Santa) Thibodeau, a local Chico Balloon Pilot join the team for the weekend. The goal was to have the balloon inflated just before they opened the gates to give rides as the spectators were milling around the static displays. Problem, the control tower was now worried we would block their view of the south approach. After discussing it with them on the radio, we figured it out and all was good. Then…RAMP CHECK!! The FAA inspector showed up and wanted the full tour. No problem really, he was a great guy from the Sacramento FSDO and had actually issued the student certificate to my Crew Person/Student Pilot Laurie Pownall a month before and they had a nice little reunion. People were showing up for our rides so we got inflated and managed to tether for 2 ¼ hours before the heat induced high fuel consumption got the best of us. Then we got to stick around and enjoyed the air show. Got there the same time on Sunday, but Sunday was even better…No ramp check!!! Instead, after seeing how much fun everyone was having with the RE/MAX Balloon, the FAA inspector brought his family out for rides. He even went too!! Once again we were able to continue for 2 ¼ hours. We (Continued on page 4) © Pacific Coast Aeronauts, November 2012 Page 3 Downwind Chase (Continued from page 3) chopped the line of people and called the tower to let them know we were done. We were out of fuel, literally on vapor. Here come some people running. Guess who, yep…the Media. No promises, but I got them aboard and burned, burned and burned. Got them up to about 80 feet just long enough to do a live interview in the air with the RE/MAX Broker.

  • Nick Saum LTA Resume
    Nicholas M. Saum, PhD Inducted into the U.S. Ballooning Hall of Fame on July 28, 2019 By the Balloon Federation of America at the National Balloon Museum in Indianola, Iowa Nicholas M. Saum, PhD, contributed selflessly to the field of aviation, and aerostation in particular, over the course of a long and colorful career. He set dozens of World and National Records in Altitude, Distance and Duration in a rozier balloon he built himself. He authored the Propane and Fuel Management handbook for the BFA, and contributed to the Balloon Flying Handbook published by the FAA. He served on the launch teams of many of Steve Fossett’s circumglobal balloon attempts, as the crew chief and launch director for the German team on the Chrysler TransAtlantic balloon race, and on Kevin Uliassi’s J. Renee 1 circumglobal attempts. He taught many students how to fly both hot air and gas balloons, and served as an FAA Designated Examiner for balloons. While Nick prided himself on his irascible manner, he was the first to step up to service, to support fellow aeronauts, to research, experiment and publish in the field of safety, and to lend his considerable intellectual prowess to the growing body of knowledge in our sport. As a young man, Nick loved to hunt pheasants and shoot skeet. He regularly participated in fox hunts, and enjoyed riding horses. He enjoyed roller skating, entering dance competitions, and tinkering with carts. After teaching himself Morse Code, Nick obtained a job with the Illinois Central Railroad. Later, in the US Army, he served as a Morse Code Interceptor in Okinawa.

  • The Struggle for Control of American Military Aviation
    THE STRUGGLE FOR CONTROL OF AMERICAN MILITARY AVIATION by PAUL HARRIS LARSON B.A., Auburn University Montgomery, 2000 M.A., Texas State University, 2002 AN ABSTRACT OF A DISSERTATION submitted in partial fulfillment of the requirements for the degree DOCTOR OF PHILOSOPHY Department of History College of Arts and Sciences KANSAS STATE UNIVERSITY Manhattan, Kansas 2016 Abstract The United States Army activated the Aeronautical Division, United States Signal Corps, on August 1, 1907. The men of the Aeronautical Division faced hardships and challenges from the very beginning as they tried to build the nation’s first air force prior to World War I. The U.S. Army, the War Department, Congress, and even the American people, really did not know what aircraft could do beyond simple flight. American airmen tried to demonstrate what air power was capable of, but the response to their achievements never met their expectations. Using an abundance of primary and secondary sources on American air power, this dissertation demonstrates that airmen’s struggle for a separate service was not something that developed slowly over the course of decades. Instead, this dissertation shows that airmen wanted independence from the U.S. Army from the start. From their point of view, the U.S. Army, the War Department, and Congress never really appreciated or understood air power. As a result, airmen became more and more alienated with each passing year until they achieve want they wanted—independence.

  • Helicopter Flying Handbook (FAA-H-8083-21B)
    Chapter 11 Helicopter Emergencies and Hazards Introduction Today, helicopters are quite reliable. However, emergencies do occur, whether a result of mechanical failure or pilot error, and should be anticipated. Regardless of the cause, the recovery needs to be quick and precise. By having a thorough knowledge of the helicopter and its systems, a pilot is able to handle the situation more readily. Helicopter emergencies and the proper recovery procedures should be discussed and, when possible, practiced in flight. In addition, by knowing the conditions that can lead to an emergency, many potential accidents can be avoided. 11-1 Autorotation Several factors affect the rate of descent in autorotation: bank angle, density altitude, gross weight, rotor rpm, trim In a helicopter, an autorotative descent is a power-off condition, and airspeed. The primary ways to control the rate maneuver in which the engine is disengaged from the of descent are with airspeed and rotor rpm. Higher or lower main rotor disk and the rotor blades are driven solely by airspeed is obtained with the cyclic pitch control just as in the upward flow of air through the rotor.

In theory, a pilot has a choice in the other words, the engine is no longer supplying power to angle of descent, varying, from straight vertical to maximum the main rotor. horizontal range (which is the minimum angle of descent). Rate of descent is high at zero airspeed and decreases to a The most common reason for an autorotation is failure of the minimum at approximately 50–60 knots, depending upon the engine or drive line, but autorotation may also be performed particular helicopter and the factors just mentioned.

  • Chapter 4: Maintaining Aircraft Control: Upset Prevention and Recovery
    Chapter 4 Maintaining Aircraft Control: Upset Prevention and Recovery Training Introduction A pilot’s fundamental responsibility is to prevent a loss of control (LOC). Loss of control in-flight (LOC-I) is the leading cause of fatal general aviation accidents in the U.S. and commercial aviation worldwide. LOC-I is defined as a significant deviation of an aircraft from the intended flightpath and it often results from an airplane upset. Maneuvering is the most common phase of flight for general aviation LOC-I accidents to occur; however, LOC-I accidents occur in all phases of flight. To prevent LOC-I accidents, it is important for pilots to recognize and maintain a heightened awareness of situations that increase the risk of loss of control. Those situations include: uncoordinated flight, equipment malfunctions, pilot complacency, distraction, turbulence, and poor risk management – like attempting to fly in instrument meteorological conditions (IMC) when the pilot is not qualified or proficient. Sadly, there are also LOC-I accidents resulting from intentional disregard or recklessness. 4-1 To maintain aircraft control when faced with these or other contributing factors, the pilot must be aware of situations where LOC-I can occur, recognize when an airplane is approaching a stall, has stalled, or is in an upset condition, and understand and execute the correct procedures to recover the aircraft. D.C. ELEC. R 6 0 ° Defining an Airplane Upset 2 MIN. NO PITCH INFORMATION The term “upset” was formally introduced by an industry L work group in 2004 in the “Pilot Guide to Airplane Upset i Recovery,” which is one part of the “Airplane Upset Recovery Training Aid.” The working group was primarily focused on large transport airplanes and sought to come up with one term to describe an “unusual attitude” or “loss of control,” for example, and to generally describe specific parameters as part of its definition.
