NASA dropped dozens of command modules out of cargo planes. How do you think the parachute system was developed and tested? How do you think the splashdown characteristics were tested?

Of course neither a test nor a fabrication would have been conducted without first clearing the airspace of commercial traffic. The "pilot" Kaysing spoke to was a caller on one of the many call-in programs Kaysing frequents. So while we can't necessarily fault Kaysing for the anonymity of the caller, we can certainly fault him for continuing to promulgate implausibilities without verification.
