DENVER (CBS4) – A cellphone may have played a role in a deadly plane crash in Adams County. 
 
 The National Transportation Safety Board released its report on the May 2014 crash in which two people were killed when the plane went down near the Front Range Airport in Watkins. 
 
 The NTSB says the plane’s occupants were taking selfies on board. The report says the cause of the crash may have been a case of distracted flying. 
 
 Investigators found a GoPro camera in the crash debris. The video from the camera showed the pilot and his passenger taking selfies at low altitudes. 
 
 The Cessna 150 went down in a field two miles from Front Range Airport while doing nighttime takeoffs and landings, according to the NTSB report. 
 
 “Pilot and passengers were taking self-photographs with their cellphones,” the report states. 
 
 The pilot and owner of the plane was 29-year-old Amritpal Singh of Aurora. Jeff Price had been one of his professors at Metro State University. He says Singh loved to fly and the aviation department newsletter had done a story about his death. 
 
 The NTSB report stated those in the plane were also using the camera’s flash function at night. Price says that can be distracting and especially dangerous at low altitudes. 
 
 Ironically, Price’s former student’s love of aviation may now turn into a cautionary tale of the dangers of using a cellphone for taking photos while flying. 
 
 Price said he was once flying a plane when somebody in the cockpit took a flash picture. He said he thought it was lightning and it greatly startled him. ||||| The plane that crashed, killing two people, on Saturday, May 31, 2014.

 "Selfies" likely contributed to a single-engine plane crash east of Denver last May that killed two people, federal investigators said in a report released last week. 
 
 The National Transportation Safety Board said a GoPro video camera was found near the plane's wreckage in Watkins, about 25 miles east of Denver. Recordings on the device showed several flights where the pilot and his passengers were taking "self-photographs" with their cellphones. 
 
 In one recording, the pilot was captured using the flash at night to take selfies during the plane's intitial climb and flight, the NTSB said. The deadly flight itself was not captured on the GoPro. 
 
 "Post-accident examination of the airplane did not reveal any pre-impact anomalies that would have precluded normal operation," the NTSB said in their report, released Friday. "Based on the wreckage distribution, which was consistent with a high-speed impact, and the degraded visual reference conditions, it is likely that the pilot experienced spatial disorientation and lost control of the airplane." 
 
 Investigators found that the plane's crash was likely caused by an aerodynamic stall and "subsequent spin into terrain."

 "It is likely that cell phone use during the accident flight distracted the pilot and contributed to the development of spatial disorientation and subsequent loss of control," the report says. 
 
 Family members said Amritpal Singh, 29, was flying the plane when it crashed, killing him. The aircraft was registered to Singh. 
 
 The plane, a Cessna-150 two-seater built in 1970, took off just after midnight on May 31, 2014 from Front Range Airport in Adams County. It was reported missing by Singh's family at 3:45 a.m. and the plane's wreckage was found at about 7:30 a.m. 
 
 Singh's family said the passenger killed in the crash was Jatinder Singh, 31. a musician in town for a concert at Adams City High School and that Amritpal Singh was giving airplane rides to some of the people in town for the concert. 
 
 The plane crashed in an open field, leaving it in a mangled ball. 
 
 "The airplane impacted a field and bounced one time before it came to rest upright," the NTSB said.

 The co-pilot of the Germanwings flight that crashed in the French Alps, named as Andreas Lubitz, appeared to want to "destroy the plane", officials said. 
 
 Marseille prosecutor Brice Robin, citing information from the "black box" voice recorder, said the co-pilot was alone in the cockpit. 
 
 He intentionally started a descent while the pilot was locked out. 
 
 Mr Robin said there was "absolute silence in the cockpit" as the pilot fought to re-enter it. 
 
 He said air traffic controllers made repeated attempts to contact the aircraft, but to no avail. Passengers could be heard screaming just before the crash, he added. 
 
 Details are emerging of the German co-pilot's past - although his apparent motives for causing the crash remain a mystery. 
 
 Live updates from the day 
 
 What happened in the final half hour? 
 
 Mr Lubitz, 27, had undergone intensive training and "was 100% fit to fly without any caveats", according to Carsten Spohr, the head of Lufthansa, the German carrier that owns Germanwings.

 Mr Spohr said Mr Lubitz's training had been interrupted for several months six years ago, but did not say why. 
 
 The training was resumed after "the suitability of the candidate was re-established", he said. 
 
 German Chancellor Angela Merkel told reporters that the co-pilot's apparent actions had given the tragedy a "new, simply incomprehensible dimension". 
 
 Police have been searching the co-pilot's home in Montabaur, near Frankfurt, as well as a flat he kept in Duesseldorf. 
 
 The Airbus 320 from Barcelona to Duesseldorf hit a mountain, killing all 144 passengers and six crew, after an eight-minute descent. 
 
 Andreas Lubitz: Germanwings co-pilot under scrutiny

 Who was Andreas Lubitz? 
 
 "We hear the pilot ask the co-pilot to take control of the plane and we hear at the same time the sound of a seat moving backwards and the sound of a door closing," Mr Robin told reporters. 
 
 He said the pilot, named in the German media as Patrick S, had probably gone to the toilet. 
 
 "At that moment, the co-pilot is controlling the plane by himself. While he is alone, the co-pilot presses the buttons of the flight monitoring system to put into action the descent of the aeroplane.

 "He operated this button for a reason we don't know yet, but it appears that the reason was to destroy this plane." 
 
 Meanwhile, online tracking service Flightradar24 said satellite data it had analysed found that someone had changed the plane's altitude from 38,000ft (11,582m) to 100ft - the minimum setting possible. 
 
 "Between 09:30:52 and 09:30:55 you can see that the autopilot was manually changed from 38,000ft to 100ft and nine seconds later the aircraft started to descend, probably with the 'open descent' autopilot setting," Flightradar24 chief Fredrik Lindahl was quoted as saying by Reuters. 
 
 Mr Lubitz was alive until the final impact, Mr Robin said. The prosecutor added that "the most plausible interpretation" was that the co-pilot had deliberately barred the pilot from re-entering the cockpit. 
 
 He added that the co-pilot was "not known by us" to have any links to extremism or terrorism.

 The focus now moves from the mechanics to the man flying the plane. An accident expert has told me the investigators will pore over the co-pilot's background and that of his family too. 
 
 Did he owe money? Was there a grudge? They'll look at his religion, whether he was in trouble with the law, whether he had a stable love life. This kind of event is rare but it has happened before, although the reasons vary widely. 
 
 After 9/11, they made cockpits impregnable. It keeps the terrorists out, but in the end it also allows someone to keep their colleagues out too. Airlines have to make a call. Which is the bigger threat - terrorism or suicide? 
 
 Passengers were not aware of the impending crash "until the very last moment" when screams could be heard, Mr Robin said, adding that they died instantly. 
 
 After Thursday's revelations, several airlines have pledged to change their rules to ensure at least two crew members are present in the cockpit at all times. 
 
 Meanwhile, relatives and friends of the victims travelled to the Alpine region where the plane came down, near the town of Seyne-les-Alpes.

 The disclosure of the likely cause of the crash has provoked anger. 
 
 "One person can't have the right to end the lives of hundreds of people and families," Esteban Rodriguez, a Spanish factory worker who lost two friends aboard the aircraft, told the Associated Press news agency. 
 
 The principal of a German high school that lost 16 pupils and two teachers in the crash said the latest news was "much, much worse than we had thought". 
 
 The second "black box" - that records flight data - has still not been found. 
 
 Other incidents thought to be caused by deliberate pilot action

– This may rank as one of the deadlier selfies-that-kill stories: The photos likely contributed to not one person's death, but two. The NTSB report on a May 31 plane crash in Watkins, Colo., cites recordings from a GoPro camera found at the scene. They show pilot Amritpal Singh, 29, and his passenger using their cellphones to take selfies. The report indicates that the phones' flashes disoriented Singh (it was sometime after 12:30am); he then lost control of the plane, reports KUSA-TV. A portion of the report via the Denver Post: "Post-accident examination of the airplane did not reveal any pre-impact anomalies that would have precluded normal operation. Based on the wreckage distribution ... and the degraded visual reference conditions, it is likely that the pilot experienced spatial disorientation and lost control of the airplane." CBS Denver notes the selfies were taken at low altitudes, and speaks with an aviation security expert who knew Singh. Jeff Price says that a camera flash can be particularly problematic at those altitudes. He recounts being in the cockpit once when a flash went off; it was as jarring as lightning, he says.
