Features of this dialogue: The tragic subject matter sets this dialogue apart. Although it appears that the dialogue was cut off by the crash, it was not. Other web pages establish that the crash was significantly later. The cause of the cutoff is unknown, but it may have been a loss of electrical power in the aircraft. This is a reminder that sometimes lack of a response does not represent refusal of a game act.
