Four whistleblowers, including current and former Boeing employees, testified Wednesday before a US Senate committee investigating "serious problems" in the production of Boeing's 737 MAX, 787 Dreamliner, and 777 aircraft. "I do not want to see the crash of a 787 or a 777," Sam Salehpour, a quality engineer with the aircraft manufacturer for seventeen years, declared to the senators.

Boeing again defended its planes Wednesday before the hearing, saying it was still "confident in the safety and durability of the 787 and 777. "There are more and more serious accusations that the safety culture at Boeing is broken and that its practices are unacceptable,' noted Democratic Senator Richard Blumenthal, chair of the commission of inquiry. Two engineers notably denied during a briefing on Monday that some 1,400 Boeing planes had significant safety flaws. The hearing will be followed by several others, with officials from Boeing and the FAA notably called to testify, said Democratic Senator Richard Blumenthal in the preamble.
