I had the same thought. This article is ten years old. If he's still alive, Loadmaster Pollack should be able to identify the other three crewmembers, assuming he still has his aircrew member's logbook. Even if he's dead, someone in his family should have the logbook. Logbooks are valued possessions. If we can get those names, we can track them (or their next of kin) down.
With the logbook, we can not only identify the crew, but the specific aircraft (by tail number) as well. This is noteworthy in that we can get the crew's maintenance write-ups after the flight, and records of any maintenance done as a result of those write-ups after the mission. This is the USAF Form 781A for that aircraft, and it should be available through the USAF Historical Research Agency at Maxwell AFB. With this, we can see if there were any maintenance issues that can tie into what was alleged to have happened.
