The "two pilots was unheard of at the time..." has always been GR BS. BOTH "Gilligan's Island" and "Lost In Space" got second pilot attempts before they finally aired.
Incorrect examples. Sherwood Schwartz kept resubmitting the Gilligan's Island pilot, and after drastically re-editing it, CBS finally picked it up. Bits of the pilot were cut into the first regular series episode, and the pilot's plot was recycled as the 1st season Christmas episode. Lost in Space has a single pilot, but changes were made for series production (addition of the Robot, Dr. Smith, etc.) and the pilot was chopped up and bits incorporated into various early episodes.
Neither is the same as shooting two wholly different pilots.
