WASHINGTON ( CNN ) -- The pilot of a doomed plane that crashed , killing 50 people , said `` Jesus Christ '' and `` We 're down , '' seconds before the plane hurtled from the night sky into a house outside Buffalo , New York , in February . An investigator walks past the wreckage from a plane crash in Clarence Center , New York , in February . The last sounds heard in the cockpit were First Officer Rebecca Shaw saying `` We 're '' and then screaming at 10:16 p.m. on February 12 , according to a transcript of the cockpit recording . Seconds earlier , the pilot , Capt . Marvin Renslow , said , `` Jesus Christ , '' as a sound `` similar to stick shaker '' was heard , the transcript said . Renslow said , `` We 're down , '' and a thump was heard before Shaw said , `` We 're '' and screamed . The National Transportation Safety Board released the transcript of the cockpit recording on Tuesday as it began a three-day hearing in Washington on the crash .

Continental Connection Flight 3407 , operated by regional carrier Colgan Air , plunged into a house in Clarence Center , New York , killing all 49 people on board and one man in the house . About five minutes before the crash , Shaw had shared with Renslow her fear of flying in icy conditions , according to the transcript . `` I do n't want to have to experience that and make those kinds of calls . You know I'dve freaked out . I'dve [ sic ] had like seen this much ice and thought , 'oh my gosh , we were going to crash , '' Shaw told Renslow . The NTSB 's preliminary investigation determined there was some ice accumulation on the Bombardier Dash 8-Q400 aircraft , but that `` icing had a minimal impact on the stall speed of the airplane . '' Watch more on the NTSB investigation » . In a story Monday , the Wall Street Journal cited investigators as saying the crash resulted from pilot Marvin Renslow 's incorrect response to the plane 's precarious drop in speed : He overrode an emergency system known as a `` stick pusher , '' which sends the plane into a dive so it can regain speed and avoid a stall . Colgan Air , the operator of Continental Connection flights , said Monday that Renslow had never trained in a flight simulator with the safety system that activated just before the plane went down . Colgan said there is no regulatory requirement that it provide hands-on training with the `` stick pusher . '' `` A stick pusher demonstrated in an aircraft simulator is not required by the FAA , '' the airline said in a statement . `` And thus was not included in Colgan 's Q400 training program . '' The Federal Aviation Administration said its standards do not require hands-on practice with the safety system . `` That 's a significant problem , '' veteran pilot Douglas Moss told CNN . Moss , an expert in stall recovery , believes flight simulator practice with a stick pusher should be mandatory for aspiring pilots . `` It 's similar to picking up and throwing a groundball in baseball . You can study it academically all you want to but you really need to develop the proficiency , the skill , the muscle memory required to do that , '' said Moss . Renslow had failed five pilot tests , known as `` check rides , '' three of which occurred before he joined the airline , Colgan Air said . Renslow had revealed only one of those failures to the airline , according to Colgan . NTSB Chairman Mark Rosenker said Tuesday that the board 's hearing will not address who is to blame for the accident . `` Over the course of this hearing , we will continue to collect information that will assist the safety board in its examination of safety issues arising from this accident , '' he said . He said those issues are : airplane performance , cold weather operations , a sterile cockpit , flight crew training and performance , and fatigue management .
