At first I thought it was Anderson (the engineer), then I checked with the Wikipedia article and it said Scott was at the controls (and yes, I'm talking about the test flight, which was a practical experiment in throwing stuff out of a 727, relax with the semantics). Wikipedia cites Himmelsbach's book. I'm certain I read somewhere that Anderson was onboard, but can't remember where I saw that. So pardon my unwillingness to check every detail. I took Wikipedia's word on it.
And I assume someone was keeping notes. It's not unreasonable. I mean, there's a report about my dad's unlicensed backyard toolshed at the local Zoning Department, so there has to be detailed documentation on this exper--er-- test flight...
