Shipping regulations were an awful lot more lax 55 years ago, and I wouldn't expect more than a handful of teenagers today to be able to give you details on shipping regulations related to shipping live animals (which, absent specific regulations on shipping humans that may or may not have been in place, seem the most relevant).
I would expect some specific regulations on shipping humans today, based on cases like this, but that's a case of "... OK, this is pretty vague in the regulations, let's make it exceedingly clear."
Indeed, when I was a kid around 1960, it was perfectly normal to see someone off on a flight by getting on the plane with them and looking around, then going to the cockpit to sit in the pilot's seat and "fly" the airplane for a minute before climbing back down the stairs to watch it take off.
