Conscious Choice cover

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.


“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

United Airlines buys 15 Boom Supersonic airplanes

United Airlines today announced that it has signed a deal with Boom Supersonic to buy fifteen of its supersonic Overture airplanes.

Under the terms of the agreement, United will purchase 15 of Boom’s ‘Overture’ airliners, once Overture meets United’s demanding safety, operating and sustainability requirements, with an option for an additional 35 aircraft. The companies will work together on meeting those requirements before delivery. Once operational, Overture is expected to be the first large commercial aircraft to be net-zero carbon from day one, optimized to run on 100% sustainable aviation fuel (SAF). It is slated to roll out in 2025, fly in 2026 and expected to carry passengers by 2029.

Boom has been developing this supersonic passenger plane since 2016, though little progress has appeared to take place during most of the last five years. This contract appears to be the company’s first real sale. It also appears that it makes United a partner in the plane’s development.

Meanwhile, another company, Aerion, is developing its own supersonic passenger jet, in partnership with Boeing and scheduled for launch in 2023.

We shall have to wait to see which company wins the race to begin commercial flights.

    Great news!

    Something to look at besides boring, also-ran twin-jets!

  • Considering sonic footprint was one of the factors in the demise of the SST, not sure ‘Boom’ is a positive PR move.,before%20two%20prototypes%20of%20the%20plane%20were%20completed.

    Sorry, that’s a long URL.

    If the company can build an SST with current environmentally-friendly tech, sign me up!

    They have rolled out the subscale XB-1 vehicle.
    Mach 2.0 to 2.2 seems to me to be a sweet spot. Sydney – L.A. or return works well considering the time zones if you depart at the right times. Need to do it non stop though.

    “Mach 2.0 to 2.2 seems to me to be a sweet spot. Sydney – L.A. or return works well considering the time zones if you depart at the right times. Need to do it non stop though.”

    Current low fare is circa $3400, second is $4300, third $4800 all for 15 hour non-stop flights with one carry on and one checked bag, one week round trip. ($9700 for 14 hour flight). The question is, at those prices, how big of a market are we talking about and what premium it is willing to pay to cut that to about 7 or so so hours (1 each subsonic departing and arriving, 5 at Mach 2)?

    We’re not talking about your average tourist, so how much business traffic is there (a woman I once knew was sent by her law firm on two day round trips to London by Concorde – hey, the customer is paying for it, so put it in the billings)(? Can you make a profit on the “carriage trade”?
