Ethiopian Airlines Plane Is the 2nd Boeing Max 8 to Crash in Months

Flight 302 — a two-hour shuttle between two of the busiest capitals in East Africa — was carrying passengers from at least four continents. The dead included 32 Kenyans, 18 Canadians, nine Ethiopians, eight each from the United States, China and Italy, and seven from Britain, the airline said. The French Foreign Ministry said nine of its citizens were aboard.

The passengers also reportedly included delegates traveling to Nairobi for a weeklong United Nations Environment Assembly that was scheduled to start on Monday.

While the cause of the crash was unclear, the disaster is certain to raise more doubts about the safety of the 737 Max 8, one of Boeing’s fastest-selling airplanes.

The plane, delivered to Ethiopian Airlines in November, was new, just like the Lion Air airplane that plunged nose down into the Java Sea last October, minutes after taking off from Jakarta, the Indonesian capital.

Flight 302 took off in good weather, but its vertical speed became unstable right after takeoff, fluctuating wildly, according to data published by FlightRadar24 on Twitter. In the first three minutes of flight, the vertical speed varied from zero feet per minute per hour to 1,472 to minus 1,920 — unusual during ascent.

“During takeoff, one would expect sustained positive vertical speed indications,” Ian Petchenik, a spokesman for FlightRadar24, said in an

Ethiopian Airline Crash Updates: Data and Voice Recorders Recovered

The F.A.A. hasn’t taken that kind of step on a fleet of aircraft since 2013, when it ordered Boeing 787s to stop flying temporarily after a problem with the plane’s battery system was identified.

The agency, which certified the latest version of Boeing’s best-selling jet as airworthy in 2017, has not taken that step with the Max 8 despite mounting questions about the plane’s safety record.

Boeing issued a statement late Monday night saying that for the past several months, in the aftermath of the crash of Lion Air Flight 610, the company has been developing a “flight control software enhancement for the 737 MAX, designed to make an already safe aircraft even safer.” According to the company, it has been working with the F.A.A. to roll out the software updates across the 737 MAX fleet in the coming weeks.

The Association of Flight Attendants sent a letter to the F.A.A. calling for a review of the Max 8. “We need help from the regulators when the entire world is looking at two catastrophic incidents that happened on the same aircraft type within five months of each other,” said Sara Nelson, the president of the flight attendants’ union. “Our system is so safe that these things don’t happen today. That is why people are questioning what is going on here.”

Pilots also raised questions. “We’re very

Ethiopian Airlines crash: FAA says U.S. airlines can still fly Boeing jet model

The Federal Aviation Administration on Monday said U.S. airlines can still fly the Boeing jet model that has been involved in two crashes in less than six months.

Its announcement came as other countries around the world — including China, Indonesia, Mexico and Argentina — grounded the Boeing 737 Max 8 and 737 Max 9 jets in their airlines’ fleets in the wake of an Ethiopian Airlines crash that killed all 157 people aboard Sunday.

The 737 Max 8 that went down in Ethiopia shortly after takeoff is that same model that crashed in Indonesia in late October, killing 189.

The FAA said the 737 Max 8 and its newer version, the Max 9, are airworthy. It also said it will closely examine all crash data in Ethiopia and take action if it is warranted.

“All data will be closely examined during this investigation, and the FAA will take appropriate action if necessary,” the agency said in a statement.

The agency noted that reports are drawing similarities between this accident and the Indonesia crash, but said “this investigation has just begun, and to date we have not been provided data to draw any conclusions or take any actions.”

Besides the FAA, commercial airlines in the U.S. and Boeing were all coming under pressure Monday to keep 737 Max jets out of the air or at least to address safety concerns while the crash investigation is ongoing.

Boeing announced Monday night that enhancements to flight-control software for

Building Stratolaunch, The Largest Airplane Ever Created

Rutan, meanwhile, was thinking about the Brobdingnagian airplane that would eventually become Stratolaunch. In 1992 he had been summoned by Antonio Elias, a senior executive at a commercial space company called Orbital Sciences Corporation, to meet with a small group. Elias was exploring the idea of building a heavy spacecraft that could be launched from a giant airplane.

One problem with ground-based rockets is that they can take off from only a small number of facilities, like the Kennedy Space Center or Vandenberg Air Force Base, where competition for launch time creates long delays. A plane-based launch would create new possibilities.

But a plane that big had other challenges. Rutan’s analysis concluded that to deliver the weight of the rocket Elias was talking about—up to 640,000 pounds—you’d need a wingspan of almost 400 feet. That wing had to be strong too. In addition to two fuselages and tons of fuel, it would be carrying a set of jet engines and that massive vehicle. Rutan planned to build the plane from nonmetal composites, rather than aluminum, to keep the weight down, but making the composite strong enough presented another problem. Rutan solved this dilemma in part with a process called pultrusion, in which a machine pulls a material at a constant rate and then bakes it until it hardens, a way to mold huge segments of the plane with a consistent strength. This technique let the engineers manufacture the very long spars that fortify the giant wing.

Rutan began working on a

U.S. Air Force installs first 3D printed metal part on F-22 fighter aircraft

The U.S. Air Force has revealed that it installed a titanium 3D printed component on an operational F-22 Raptor fighter aircraft this past December. The 3D printed part, a secondary bracket component, enabled Air Force technicians speed up the replacement of a damaged part on the aircraft.

Manufactured by Lockheed Martin and Boeing, the F-22 Raptor is a single-seat, twin-engine, all-weather stealth tactical fighter aircraft utilized by the U.S. Air Force. The aircraft, which saw its first flight in 1997, went out of production in 2011 for various reasons, though operational units are still in use.

This situation has inevitably come with certain challenges, especially when it comes to repairing or replacing parts in the F-22. 3D printing, as it turns out, has provided a viable solution by offering on-demand production capabilities.

The 3D printed bracket was installed by the 574th Aircraft Maintenance Squadron onto an operational F-22 Raptor during depot maintenance at Hill Air Force Base. Robert Lewin, 574th AMXS director, commented: “One of the most difficult things to overcome in the F-22 community, because of the small fleet size, is the availability of additional parts to support the aircraft.”

3D printing enabled the team to print a replacement bracket on demand and as a one-off, saving substantial time and money. Importantly, being able to produce and

China, Ethiopia order MAX 8 planes grounded after crash


BEIJING (AP) — China’s civilian aviation authority ordered all Chinese airlines to ground their Boeing 737 Max 8 planes indefinitely on Monday after one of the aircraft crashed in Ethiopia.

The crash of the Ethiopian Airlines jet shortly after it took off from Addis Ababa is drawing renewed scrutiny of the plane just four months after a crash of the same model of aircraft in Indonesia.

Meanwhile, a spokesman for Ethiopian Airlines, Asrat Begashaw, said the carrier had grounded its remaining four 737 Max 8 planes until further notice as an “extra safety precaution.”

The airline was using five new 737 Max 8s and awaiting delivery of 25 more. Begashaw said the search for body parts and debris from the crash was continui

Sears kit homes still standing in neighborhoods throughout central Ohio

Mail-order homes sold by Sears, Roebuck and Co. in the early 20th century have proven more durable and enduring than the company itself.

Sears declared bankruptcy late last year, and most stores operated by the venerable retailer have closed. But thousands of Sears homes, sold through catalogs between 1908 and the early 1940s, still stand across the country, hundreds of them in central Ohio.

“I’m an old-house fan,” said Martin Granneman, the owner of a Sears kit house built in 1927 on McNaughten Road.

Granneman and his wife, Julia, bought the house in 1993.

“When this property came available, I knew it was a Sears house,” Mr. Granneman, 50, said.

“I’m from North Ridgeville (Ohio), and there are several Sears houses there that have the same footprint as ours.”

He identified the house as a Sears “Vallonia” bungalow by the model’s picture in a reproduction of an antique Sears home catalog, he said.

Cindy Catanzaro, who lives in Springfield, maintains the website searshousesinohio.wordpress.com.

Catanzaro has used property records and other resources to identify more than 200 probable Sears houses in Franklin County.

She got hooked on the topic after she bought a small home in Springfield that she later learned was a Sears house, she said.

“So I began researching and found out there was another one across the street, then another down the street. It just snowballed.”

“When I ran out of houses to find in Clark County, I expanded” to find Sears houses all over
