The difference is that it requires a change to the laws of physics as we know them for mock airstrips and antennas made of bamboo to work, wheras it requires a change to the laws of physics as we know them for cryonic preservation of information to not work.
Cryonicists might not know the exact details or best approach to take, but they're at least starting from a platform of 'physics allows this'. I also have a lot of difficulty blaming them for being non-experts, given the social stigmas around cryonics and death. Expect that to change over the coming decades.

Not in the knowledge of those who used to build them. Well, technically they didn't have a concept of "laws of physics", but obviously they had a system of epistemic beliefs which had to take into account the undeniable observation that aeroplanes full of goods appeared at some point.
These people didn't really understand the phenomenon, but it was very emotionally relevant to them, hence they tried to elicit ...

- First "official" program to practice suspended animation
- The article naturally goes on to ask whether longer SA (months, years) is possible
- Amazing quote: "Every day at work I declare people dead. They have no signs of life, no heartbeat, no brain activity. I sign a piece of paper knowing in my heart that they are not actually dead. I could, right then and there, suspend them. But I have to put them in a body bag. It's frustrating to know there's a solution."
- IMO this if (I hope!) successful, will go a long way to bridge the emotional gap for cryonics
