It has happened today: a commercial aircraft – US Airways jet (A320) – has been compelled to land or ditch into the Hudson river as you can see on the last three videos. The aircraft has lost both engines after passing into a flock of birds. The pilot then carried out a perfect – as smooth as possible – ditching. Just a leg broken reported, a few injuries, nothing more even though the passengers had to walk along the wings in the frigid waters… That is the good news of the day!
Very special thanks to « Chacko » who added further information in the comments: « This guy Chelsey B. « Sully » Sullenberger, who put the plane in the water today is is an US Air Force Academy graduate who served in the Air Force from 1973 to 1980. He was an U.S. Air Force F-4 Phantom II fighter pilot who served as a flight leader and training officer in Europe and the Pacific.He was also the Blue Force mission commander during Red Flag exercises at Nellis Air Force Base, Nev. This is as per the USAF press service. »
Birth of Manned Rocket Research Airplanes: 1946 to 1975
The first reliable, effective rocket engine that would provide boost for experimental research aircraft was produced by four members of the American Rocket Society (ARS) who combined forces to form Reaction Motors Incorporated (RMI) (Rockaway, New Jersey) for developing the Experimental Liquid Rocket (XLR-11) rocket motor. The XLR-11 engine had four separate rocket chambers. Each chamber provided 1500 lb of rated thrust and could be operated independently as a means of throttling thrust in quarters, up to 6000 pounds. The XLR-11 possessed remarkable longevity, powering an impressive fleet of rocket aircraft for more than a quarter of a century (1946 to 1975). This fleet of vehicles were the first rocket aircraft devoted solely to high performance experimental flight research. They were not constrained by military or commercial demands and ranged from being the first to break the sound barrier (XS-1), to the first to reach Mach 2.0 (D-558-II [fig. 5]), to the first to exceed the X-2 Mach 3.2 record (X-15 with two XLR-11 engines).

The X-1E – Early Development of Energy Management
Design efforts to extend aircraft performance produced increased wing loadings, W/S, and decreased lift-to-drag ratios, L/D. These design changes were beneficial in reducing drag to achieve supersonic and hypersonic speeds, but were also detrimental in that they reduced the area of the maneuvering footprint and presented difficulties in the approach and landing.
As L/D values decreased, the glide slope angle and the rate of descent increased, making it more difficult for pilots to estimate distances and times required for acceptable landings. The X-1E (fig. 6) was modified with a low-aspect-ratio wing having a thickness-to-chord ratio of four percent – the only aircraft of the X-1/D-558 series to have sufficiently low L/D values to require unique energy management techniques. This X-1E was the first to experiment with approach patterns designed to give the pilot more time in the traffic pattern to manage energy.
The landing pattern was approached in a conventional manner except that altitudes and speeds were somewhat higher than for powered aircraft. The initial reference point was established at 12,000 ft (mean sea level) on a downwind heading (180 deg remaining to turn). The downwind leg was offset some four miles from the centerline of the landing runway. On downwind, abeam the touchdown point, landing gear and partial flaps were deployed at a speed of 240 knots. Full flaps were usually deployed on the final approach. At the initial reference point the pilot had almost three minutes until touchdown – additional time for handling increased speeds and sink rates.7,8
A few days after he succeeded in crossing the Channel, I thought it was time to show who and what gave Yves Rossy the incentive to perform such breathtaking feats. Let’s have a look at this hero’s career.
When he was a child, he said « When I am older, I will be pilots » – with an S ! This became his motto from the day he got unable to go down from a tree by himself. The child has now become « Fusionman ». In order to understand what motivated this pilot, watch and listen to Yves Rossy’s comments (in French) on the video below:
As he explained, Yves Rossy has always admired the first pioneers. Every attempt used to end by death or breakthrough. Yves Rossy has now become « Fusionman », the first man flushed in a jet-engine-propelled wing, flying as if he were Icarus.
Yves Rossy was born on the 27th of August 1959 in Neufchatel – Switzerland. Both gazing skywards, and having his feet firmly planted on the ground, he was taught technical education and passed a mechanics baccalauréat. Natural-born sportsman, he has practised everything that glides, slides, or flies – surfing, waterskiing, wakeboarding, skysurfing, parachuting, aerobatics, motorcycling, rafting, hang-gliding, etc. Flying with a jet-powered wing is the crowning of a 30-year career and numerous stunts, feats, and premieres.
Certainly one of the most intense periods in his career. Yves Rossy flew the supersonic Mirage III for 15 years. During this period, he flew some historical aircraft such as the Hunter or the Venom, one of the first English jet-engine fighters. He got the idea of going round Switzerland throughout several activities within a day. He carried out this feat on the 3rd of July 1991. During his trip, he flew a DC-9, went motorcycling, skiing, snowboarding, mountaineering, paragliding, mountain-biking, bungee-jumping, he flew a helicopter, went skydiving, rafting, hydrospeeding, canoeing, drove a sportscar, went hang-gliding, horse-riding, barefooting, waterskiing, wakeboarding, and finally speedboating – that’s enough… 25 vehicles were used this day along 1,000 km for 15 hours and a half! Yves Rossy is a Swiss Air Force retiree, and keeps flying the two-seater Hunter belonging to the association Amici del Hunter. He works as a captain at Swiss Airlines, and his spare-time is dedicated to his passion. He has been supported since February 2007 by Jean-Claude BIVER, HUBLOT watches’ CEO.
HE FANCIES DOING WHAT NEVER HAPPENED BEFORE
Yves Rossy is used to venturing off the beaten tracks. He devotes all his hobbies to flight in all its forms. He multiplies the tests on contrivances that change with the passing experiments. An inflatable wing made him get over the 12-kilometer distance between the two shores of Lake Geneva. Many stunts were reported such as hang-gliding over the huge Geneva spray to surf on top of it, then land on the lake to grab a waterskiing handle, and get to the shore without getting wet! Another feat – he skydived on a disk over the Matterhorn. As Yves Rossy whished to get beyond his feats and dreams, he wanted to fly with as little instrumentation as possible – like a bird with the ability to move and steer into space, he got the idea of adding scale model jet engines under a wing.
The first attempt occurred in March, 2003. The German Jet-Cat company supplied the engines which were added under an inflatable wing, but this trial was a failure for lacking of rigidity. He developed a rigid spreadable carbon wing built-up at ACT Composites’ in 2004. It made an indifferent start. He spun and had to drop his wing at Al-Ain airshow. The wing parachute tore, and the device was damaged. From that time, the pilot worked hard to improve the spreading of the wing and aerodynamics at the wing tips in order to provide more stability. He achieved two flights with a two-jet-engine-propelled wing in 2005. He had a narrow shave a month later: an uncontrollable sway led him to drop his wing which crashed. After a long year and two extra jet engines added, the wing became more secure. As a matter of fact, the 5’40 » over Bex – Switzerland – came up as an awaken dream for this pioneer. Since then, Yves Rossy has relentlessly been training to optimize his wing. Yves was compelled again to drop his prototype wing while in a new test flight in April 2007. The wing was seriously damaged and took a few months to be repaired. In the aftermath of this failure, Yves Rossy decided to build up a new, more reliable, higher-performance wing. Since early 2008, his wings have become more and more sophisticated.
Finally, Yves « Fusionman » « Rocketman » « Jetman » Rossy found his place in Aviation History on the 26th of September 2008, having joined Calais – France – to Dover – England. Congratulations to Yves Rossy and thanks to MEDIA IMPACT and its staff which supplied me with materials and information to write a post about Yves Rossy.
Michel Fournier tested his radio connection that also will ensure physiological monitoring, as a video connection through the helmet onboard his « gondola » was tested too. Everything looked OK, but the weather compelled to postpone the Frenchman’s feat a bit later. Now it looks OK again.
64-year old parachutist Michel FOURNIER should presently jump at a speed of 1.4 Mach at Flight Level 1320 (about 40 km, or 132,000 ft), almost over the ozone layer !!!
GO MICHEL ! GO and make a historical sonic boom as Chuck Yeager did!
The balloon is being inflated. Wait and see…
