Junk Your Juniper In Reno And Receive A Free Defensible Space

Reno area residents are being encouraged to “Junk The Junipers” Sunday in an effort to modify ornamental landscaping around homes and buildings to help reduce the threat of a wildland fire destroying structures.

Pinon juniper trees were the main fuel source in the recent Como Fire east of Carson City.

Flammable juniper plants placed adjacent to homes and other structures can significantly contribute to the spread of a wildland fire to those structures. Residents are being asked to remove junipers from around their home and bring them to one of two Moana Nursery locations.  Each Moana Nursery location will exchange the junipers for a replacement plant on a one plant per household basis.  Each location will have up 50 plants to exchange throughout the day until gone.

This is the second year for the program, coordinated by the University of Nevada Cooperative Extension, in which the Reno Fire Department has partnered with Moana Nursery, to hold the “Junk The Junipers” day at the Moana Nursery locations at 11000 West Moana Lane and 11301 South Virginia Street.

This event is part of Nevada Wildfire Awareness Week observances May 17-24.  Information on creating defensible space around your home will also be available from the Living With Fire program. To go to their web site click here.

The Junk The Juniper event has been developed to help increase community awareness of the flammability of some ornamental plants used in landscaping.  Sponsors of the program hope that area residents will also consider modification of landscaping to include more fire resistive plants around their homes to eliminate junipers and other flammable vegetation and implement measures that can help reduce the intensity and spread of wildland fires and the potential extension of fire to homes and other structures.

Investigators in 777 crash looking at fuel systems

Investigators studying last week’s crash landing of a British Airways Boeing 777 said Wednesday they are looking closely at the possibility that the accident was caused by an interruption in the flow of jet fuel to the engines.

The cause of the Jan. 17 crash at London’s Heathrow airport has not been established. Even if it is a fuel-flow interruption, that doesn’t necessarily exonerate Boeing.

But this focus of the investigation seems to increase the possibility of an external cause such as contamination of jet fuel loaded before the 777 took off from Beijing.

Alternative scenarios, such as a software control-system failure, clearly would be the manufacturer’s responsibility and could bring into question the safety of the airplane.

“All possible scenarios that could explain the thrust reduction and continued lack of response of the engines” are being examined, the U.K.’s Air Accidents Investigation Branch said Wednesday. “This work includes a detailed analysis and examination of the complete fuel-flow path from the aircraft tanks to the engine-fuel nozzles.”

The plane, carrying 136 passengers and a crew of 16, lost power about 2 miles from touchdown at a height of 600 feet. It was the first crash in the more than a dozen years that airlines have flown the 777.

The U.K. agency leading the investigation made clear that, contrary to some initial reports, the jet’s two Rolls-Royce engines did not fail at precisely the same moment, and neither failed completely.

The aircraft was approaching with the autopilot engaged when the autothrust system commanded the pilot to increase thrust from both engines.

“The engines both initially responded but after about 3 seconds the thrust of the right engine reduced,” the report said. “Some eight seconds later the thrust reduced on the left engine to a similar level. … Both engines continued to produce thrust at an engine speed above flight idle, but less than the commanded thrust.”

The accident resulted in few injuries. The co-pilot was credited with heroic skill in keeping the plane aloft over nearby houses and putting it down onto the grass 1,000 feet short of the runway.

The report said that “the autothrottle and engine-control commands were performing as expected prior to, and after, the reduction in thrust,” suggesting that the primary software controlling the system functioned as it should.

Singling out fuel flow suggests investigators are zeroing in either on fuel contamination perhaps from an external fuel source or maybe from some internal leakage of other fluid into the fuel tanks or on some leakage in a fuel line serving both engines.
