This is quite interesting. However I think another good use would be to pre-load the passengers into these pods, and then attach it to the plane for take off.

This is quite interesting. However I think another good use would be to pre-load the passengers into these pods, and then attach it to the plane for take off. That way you could probably make things a bit more efficient. Maybe just for cargo since passengers might have a lot of use cases not covered by this design but I'm guessing for loading and unloading ship containers it could work. Probably it's an engineering challenge not worth the cost (yet), but it definitely looks like something could be worked out starting with this idea, no?
