Narrative:

I'm a crew member with another major carrier. On the date listed above, I filled out the paperwork to ride jumpseat/available seat in back on another carrier from cvg. The crew was running late due to a maintenance problem with another aircraft. After a brief introduction and identify check, the captain invited me to situation in the cabin. I took a seat (window) on aircraft's left -- 2 rows aft of the emergency exit row. The crew cranked the right engine on pushback, after disconnect, pwred up more than usual to taxi, and while taxiing cranked the left engine. A crew member requested the flight attendants be seated, and we taxied on the runway. Having arose myself at XA50 for the commute, I wasn't paying much attention to their operation until they pushed the power up for takeoff and at the same time, the jack screw started to extend takeoff flaps! This crew did not make any effort to abort the takeoff as the flaps reached takeoff position at approximately 80-100 KTS! Obviously, the takeoff warning horn saved all aboard from a terrible mishap. Not being on the flight deck, I can only assume that the crew didn't complete the before takeoff checklist. Additional unbelievable events included the crew continuing the takeoff roll while the flaps extended, rather than following procedure and exiting the runway to examine why they got a takeoff warning horn in the first place. As I exited the aircraft, no mention was made of the event. In the days of CRM and checklist compliance, it's pretty difficult to believe an event like this would take place.

Title: A B737-200 FLT CREW IS NOTED, BY A DEADHEADING CAPT, TO PERFORM A ROLLING TKOF WITHOUT FLAPS BEING EXTENDED UNTIL AFTER THROTTLE ADVANCEMENT, EXTENDING FULLY AROUND 90 KTS AT CVG, KY.

Narrative: I'M A CREW MEMBER WITH ANOTHER MAJOR CARRIER. ON THE DATE LISTED ABOVE, I FILLED OUT THE PAPERWORK TO RIDE JUMPSEAT/AVAILABLE SEAT IN BACK ON ANOTHER CARRIER FROM CVG. THE CREW WAS RUNNING LATE DUE TO A MAINT PROB WITH ANOTHER ACFT. AFTER A BRIEF INTRODUCTION AND IDENT CHK, THE CAPT INVITED ME TO SIT IN THE CABIN. I TOOK A SEAT (WINDOW) ON ACFT'S L -- 2 ROWS AFT OF THE EMER EXIT ROW. THE CREW CRANKED THE R ENG ON PUSHBACK, AFTER DISCONNECT, PWRED UP MORE THAN USUAL TO TAXI, AND WHILE TAXIING CRANKED THE L ENG. A CREW MEMBER REQUESTED THE FLT ATTENDANTS BE SEATED, AND WE TAXIED ON THE RWY. HAVING AROSE MYSELF AT XA50 FOR THE COMMUTE, I WASN'T PAYING MUCH ATTN TO THEIR OP UNTIL THEY PUSHED THE PWR UP FOR TKOF AND AT THE SAME TIME, THE JACK SCREW STARTED TO EXTEND TKOF FLAPS! THIS CREW DID NOT MAKE ANY EFFORT TO ABORT THE TKOF AS THE FLAPS REACHED TKOF POS AT APPROX 80-100 KTS! OBVIOUSLY, THE TKOF WARNING HORN SAVED ALL ABOARD FROM A TERRIBLE MISHAP. NOT BEING ON THE FLT DECK, I CAN ONLY ASSUME THAT THE CREW DIDN'T COMPLETE THE BEFORE TKOF CHKLIST. ADDITIONAL UNBELIEVABLE EVENTS INCLUDED THE CREW CONTINUING THE TKOF ROLL WHILE THE FLAPS EXTENDED, RATHER THAN FOLLOWING PROC AND EXITING THE RWY TO EXAMINE WHY THEY GOT A TKOF WARNING HORN IN THE FIRST PLACE. AS I EXITED THE ACFT, NO MENTION WAS MADE OF THE EVENT. IN THE DAYS OF CRM AND CHKLIST COMPLIANCE, IT'S PRETTY DIFFICULT TO BELIEVE AN EVENT LIKE THIS WOULD TAKE PLACE.
