Part 7/9:
To substantiate their claims, the speaker cites Paul Thuma, an expert pilot and operation supervisor. Thuma's testimony indicates that an ELT in a Boeing 767 cannot be manually activated by pilots but may only trigger upon a significant impact. He relays that during the testing phase, such devices are only activated for five seconds each hour, contradicting claims of manual trigger mechanisms. Furthermore, Thuma explains that a hard landing or turn would not suffice to activate an ELT in Boeing 767s, corroborating the speaker's points and adding another layer of complexity to the discussion.
