The TV station and the federal investigative agency have both apologized for the report.
"We have a lot of good people here at KTVU Channel 2. We pride ourselves on getting it right and having the highest of standards and integrity," the station said in an on-air apology Friday later uploaded to its website. "Clearly, on Friday, that didn't happen. So again, from everyone here at KTVU, we offer our sincerest apology."
The NTSB has said that the bogus names were confirmed by an unidentified summer intern. That person is no longer serving as an intern at the NTSB.
"Earlier today, in response to an inquiry from a media outlet, a summer intern acted outside the scope of his authority when he erroneously confirmed the names of the flight crew on the aircraft," the NTSB said Friday.
"The National Transportation Safety Board apologizes for inaccurate and offensive names that were mistakenly confirmed as those of the pilots of Asiana flight 214, which crashed at San Francisco International Airport on July 6," the statement said.

The phony names, which could be seen as Asian-stereotype spellings of phrases like "Something Wrong" and "We Too Low," were read by an anchor during KTVU's noon broadcast Friday.
The anchor, Tori Campbell, later in the broadcast said the names "were not accurate despite an NTSB official in Washington confirming them late this morning."
"We apologize for this error," she said.
Kelly Nantel, a spokeswoman for the NTSB, told Reuters that the intern was a student volunteer who fielded phone calls but was instructed to transfer questions to official media representatives at the agency.
