After a few minutes, the NASA research pilot edged the DC-8 behind the MAX, trailing about a mile and a half or so. It was another in a slew of test flights in October that he’d spent riding the 737’s bumper in NASA’s venerable DC-8 research aircraft.
The former U.S. Navy aviator eased the workhorse into a slot of calmer air in the 737’s wake, he said. “…[I]n that sweet spot of that secondary (wake) and just above the primary wake is where we lived the whole time and got the best science that they really loved the entire time we were out there.”
NASA and Boeing collaborated on the flights to test the effect of sustainable aviation fuels (SAF) on the formation of contrails, short for condensation trails, which climatologists contribute to global warming. The 737-10 alternated between burning jet fuel and 100% SAF, while the DC-8 sampled the air in its wake.
Summary
- Researchers say data collected will help predict when and how contrails form and SAF’s effects on contrails.
- How much contrails contribute to global warming is not completely clear.
- Boeing is working with supply chain to develop airplanes that can fly 100% SAF and traditional jet fuel by 2030.
Pontifications: Alabama loses key committee slot in US Senate following election
By Scott Hamilton
Dec. 18, 2017, © Leeham Co.: The special US Senate election last week in Alabama drew world attention of the showdown between Democrat Doug Jones and Republican Roy Moore.
Jones eked out a victory, becoming the first Democrat in 25 years to be elected to the Senate from Alabama.
I’m not going to get into all the issues, allegations and political implications of this race. Instead, a new item from Defense News caught my eye about the implications to the Alabama aerospace position in Congress.
Defense News’ headline is eye-catching: “Election leaves Alabama-shaped hole on Senate Armed Services Committee.”
Pontifications: Small Mississippi airport plays key role in state’s aerospace industry
By Scott Hamilton
Nov. 6, 2017, © Leeham Co.: One of my stops during my October visit along the I-10 corridor from Mobile (AL) to New Orleans, through Mississippi, visiting aerospace interests was the Stennis International Airport.
The airport is in Hancock County, an hour’s drive east of New Orleans.
This is on the eastern edge of the Stennis Space Center I wrote about last week and it benefits from being in the Space Center’s shadow. The Space Center is exempt from noise regulations. So is the airport, which enables this one-runway field to be a way point for noisy military jets and trainers and a training location for helicopter-based special forces. These are all noisy aircraft that locals view as routine, says Kevin Carlisle, director of the airport.
Suppliers conference in Mobile focuses on US aerospace sector in Southeast

Oct. 31, 2017: A new event, the Southeast Aerospace and Defence Conference (SADC) scheduled for June 25-27 in Mobile (AL), will examine the commercial, defense, space and corporate aerospace sectors in the US Southeast.
The conference is organized by Airfinance Journal and Leeham Co., the first joint venture between the two companies.
The US Southeast is a growing aerospace center. Defense and space clusters have decades-long histories in the Southeast. Corporate and commercial clusters are more recent developments, albeit in some cases now well within a second decade.
Airbus’ A320 family Final Assembly Line in Mobile opened in September 2015. The FAL is producing 3.5 A320s per month and will reach its initial target of 4/mo by year end, slightly ahead of schedule. There is land capacity to expand to 8/mo.
Earlier this month, Airbus and Bombardier announced that their new venture will establish an FAL in Mobile.
Pontifications: Going to space through Mississippi
By Scott Hamilton
Oct. 30, 2017, © Leeham Co., Hancock County (MS): The US Space Shuttle program ended in 2011 and NASA is sending US astronauts to the International Space Station using Russian-made rockets.
But officials want to end reliance on those launch vehicles and are working with US companies to supply the boosters and prepare for a mission to Mars.
Last week, I wrote about Boeing’s efforts to develop the Space Launch System (SLS). I spent the week of Oct. 9 going from Mobile (AL) through the I-10 corridor in Mississippi and ending in New Orleans, gaining a high level understanding of the aerospace footprint in the US Southeast.
The Mississippi portion was arranged by the Mississippi Development Authority. I’ll provide additional reporting in the coming weeks. This week, I focus on NASA’s John C. Stennis Space Center in Hancock County (MS), an hour’s drive east of New Orleans.
US ponders Russia sanctions, some affecting US aerospace
Oct. 27, 2017, © Leeham Co.: The US is considering new trade sanctions against Russia, and Russia is considering retaliatory sanctions, that could have major implications in US aerospace—including on Boeing.
The US sanctions would be for meddling in the US presidential election in 2016 and for activities in Eastern Europe. The Russian sanctions are a tit-for-tat retaliation if the US sanctions are adopted.
Among the Russian companies that may be targeted:
Pontifications: Boeing’s focus on going to Mars

program.
But it’s one of the greatest and most exciting challenges of today’s science community.
In a speech before the annual conference of the Aerospace Alliance Oct. 12 in New Orleans, Shannon used illustrations to explain the challenges of going to Mars. Some of the art he used are contained in this presentation (NASA Space Launch System). Boeing did not make its presentation available.
The SLS, or Space Launch System, is larger than the Saturn 5 rocket used in the Apollo astronaut and Skylab space programs in the 1960s and 1970s. It was used to send Apollo to the moon and it was the only rocket capable of launching beyond low earth orbit.
Boeing is building the rocket, which will be capable of sending supplies to Mars, followed by astronauts.
