Boundary folk in America ?

What time period?
And which boundary - internal or external?
In 1947 he became the first pilot to travel faster than sound Mach 1 in level flight and ascent. Although Scott Crossfield was the first man to fly faster than Mach 2, Yeager shortly thereafter exceeded Mach 2.4.
That would be a cool job to have.On November 20, 1953, he [Crossfield] became the first man to fly at twice the speed of sound as he piloted the Skyrocket to a speed of 1,291 mph (2,078 km/h, Mach 2.005). The Skyrocket D-558-II surpassed its intended design speed by 25 percent on that day. With 99 flights in the rocket-powered X-1 and D-558-II, he had — by a wide margin — more experience with rocketplanes than any other pilot in the world by the time he left Edwards to join North American Aviation in 1955. As North American's chief engineering test pilot, he played a major role in the design and development of the X-15 and its systems. Once it was ready to fly, it was his job to demonstrate its airworthiness at speeds ranging up to Mach 3 (2,290 mph). Because the X-15 and its systems were unproven, these tests were considered extremely hazardous. Crossfield flew 14 of the 199 total X-15 flight tests with most of these tests establishing and validating initial key parameters. Scott Crossfield not only designed the X-15 from the beginning, but introduced many innovations, to include putting engine controls of the rocket plane into the cockpit. Previously, all engine adjustments resulted from technicians making adjustments on the ground based upon results of flight profiles.

as in °F. You have a fever! and 102.9 is significant in an adult. Take ibuprofen or English equivalent, drink plenty of fluids (water and/or fruit juices), put a cold compress on your forehead.wolram said:102.9 my head head hurts.
So were Mason and Dixon.The clue is in America.
http://www.creax.com/Results.aspx?id=3982The upturned wings resemble those of Boeing's upcoming 787 Dreamliner, a super-efficient design that's been exceeding the company's sales expectations thus far. The 747-8's new wings, along with quieter and cleaner-running jet engines, make it more environmentally friendly because it will burn a lot less fuel, with a corresponding reduction in exhaust. Expect the first freighter versions of this plane to be rolled out in 2009, with passenger versions to follow.
Moridin said:USS Seawolf has a length of 102.9 meters and was the Navy's second nuclear-powered attack submarine. Although it was decommissioned back in the 80s.
Yeah, this doesn't fit many of the clues though.

The A-3 is an airborne jamming aircraft originally ordered by the US Navy during the 1950s. The type is now retired from front-line service though a handful are still used for testing purposes by the defense contractor Raytheon.
The A-3 was equipped with two Pratt & Whitney J57 turbojets like that pictured below. The J57 dates to the early 1950s and is rather antiquated by today's standards.
Moridin said:The PW J57 engine has an overall diameter of 102.9 cm.
