Combination of factors behind Balado plane crash

A plane crash at a Perth and Kinross airfield was caused by a combination of factors, a report has said.

The 60-year-old pilot and a passenger were touching down at Balado following a flight from the Isle of Bute on November 30.

However, when they grounded damage was caused to the propeller and landing gear of the Pegasus Quik aircraft.

In a report published by the air accidents investigation branch, it was concluded low sun, soft ground and a phenomenon known as “sink”, where air travels downwards, all played a part in the incident…

Help! The Driver Who Caused the Accident is Blaming it on the Sun! | Barry P. Goldberg

While many Woodland Hills drivers are unlikely to complain about treacherous driving conditions caused by snow and heavy rain, they may face an unexpected hazard on the road: sun glare. Sun glare occurs when the sun is rising or setting and it effectively blinds a driver on the road.  Even if you try to make adjustments by pulling down the driver’s side visor or leaning forward, an auto accident can occur. Most drivers do not anticipate sun glare and thus do not have enough time to react when the sun overtakes them…

Hagerstown Resident Killed In Dump Truck Accident

Maryland State Police have confirmed that one man is dead after a one-vehicle accident near mile marker 28 on I-70 eastbound this morning.

Around 7:30 a.m., a man operating a dump truck was traveling east on I-70 when traffic in front of him began to slow down. The driver hit his brakes in order to avoid collision but ended up skidding off the road into an embankment.
The driver was identified as Hagerstown resident James Kendle, 73...

Troopers said Kendle, who was not wearing his seatbelt, was ejected from the dump truck that overturned on top of him before turning itself back onto its wheels.

“A truck inspection is going to be done by the commercial motor vehicle enforcement division of the Maryland State Police," said Senior Trooper Andre Butler of the Maryland State Police. "The investigation is still going on to see if there are any other factors involved. This time of year there is sun glare, the sun rises directly in front of the eastbound traffic. That may have been a factor, but we're still investigating that."…

Blinded by the Light: Sun Glare and Traffic Accidents | Baltimore Legal Examiner

Driving with sun glare is not a new hazard. It is only one of the many challenges that drivers have to overcome, with the help of a car visor, wiper fluid, polarized sunglasses, or just plain squinting.

Spring is the peak season for sun glare since the sun stays in its lowest position during morning and evening rush hours.  Driving on a clear, sunny day carries a risk of being temporarily blinded by the sun, creating an abrupt loss of visibility that makes a vehicle collision more likely.

How the Sun Can Make Driving Difficult

Although natural light typically aids a driver’s visibility, there are a number of ways bright sun can make driving more difficult, including:

  • Interfering with a driver’s vision, even if it comes through a side window or is reflected off a mirrored building or another vehicle
  • Causing a blinding effect when sunlight is refracted within the glass on a dirty, pitted, or cracked windshield
  • Limiting the driver’s vision to only the roadway ahead when he uses the car’s visor to try and block out the sun…

Defense: Sun's glare could have caused crash that killed El Paso police officer | KFOX

The defense argues weather conditions could have caused the crash that killed El Paso police Officer Angel Garcia. This is new testimony in the civil trial into Garcia's death.

As KFOX14 reported, Garcia, 27, died in the line of duty while attempting to remove a ladder from Interstate 10 near the Hawkins Exit in December 2012. Garcia's death was the result of a three-car collision allegedly caused by a tractor-trailer.

Garcia's parents, Elsa and Miguel Garcia, are suing the driver of the tractor-trailer, Harvey Hall, and the company he works for, Old Dominion Freight Line, Inc., for emotional and financial damages. The family is asking for $30 million.

Hall's attorney, Darryl Vereen, made his case to the jury that the sun's glare affected how far ahead Hall could see on I-10 when the crash happened. Vereen said Hall has maintained he could not see Garcia's police car before the crash…

Edmonton man guilty of impaired driving causing death

An Edmonton man who fatally struck an elderly woman in a west-end crosswalk was convicted Monday of impaired driving causing death.

Sivakumar Devarajah, 55, was also found guilty of driving over .08 causing death in connection with the Feb. 4, 2013, collision that killed Agnes Morgan, 77.

Court of Queen's Bench Justice Donald Manderscheid ruled that Devarajah's driving was "negligent and faulty" and said his impairment by alcohol at the time was a "significant" cause of the deadly collision.

Manderscheid rejected Devarajah's claim that the blinding sun had blocked his view of Morgan as she began walking through the crosswalk, saying others were able to see the senior and noting he had failed to lower his visor…

Judge sentences woman for crash that killed 3-yr-old via @KDVR

A plea agreement for the 78-year-old driver charged with hitting and killing a 3-year-old boy as he crossed a street was rejected by a Denver County Court judge on Thursday and she was sentenced to one day in jail.

Joan Hinkemeyer was charged with careless driving resulting in death and two counts of careless driving resulting in injury for the fatal collision on Feb. 13 at East Ohio Avenue and South University Boulevard, outside the popular Bonnie Brae Ice Cream store.

Prosecutors said Hinkemeyer was turning left from Ohio onto University when she struck 3-year-old Austin Strasser, his sister and his mother as they crossed in a crosswalk. Hinkemeyer said she couldn’t see the family because of sun glare, according to a police report…

@SgtJackWest: Placing your child's car seat, rear centre, will help prevent injury from a side impact.

> @SunPosition: Would that affect how side airbags work?

> @SgtJackWest: Hi Ralph, I've consulted with our Recon, rear side air bags will still deploy with child seat centered in rear.

> @SunPosition: Thanks Sergeant.  Good to know.

My front collision avoidance system kicked in rounding curve towards rising sun. Scared daylights out of me. Pun intended.
