A bigger plane falls victim to the square cube law - as it gets bigger the support structures need to get bigger too. At least that’s my hypothesis, clearly the article didn’t mention this. I’m curious if multiple smaller planes allows each plane to be lighter weight relative to the cargo capacity, with the front plane just sporting an engine overspend to its own size/weight.

Cheaper upfront costs. Engines alone are very expensive and require a lot of maintenance. This would increase the capacity for any freight carrier very cheaply.

It would be particularly advantageous for short term increases in freight. People buying gifts at Christmas, natural disasters, medical events like COVID etc.

The alternative would be a second aircraft, that would also need more fuel than a single aircraft.

The idea of dropping off a pod en-route to independently land is nice though

Hey it's slip coaches all over again!

Real talk, I could see something like this adding some efficiency, but I can't imagine these trailers landing at a regular commercial airport without a crew and power to abort the landing and circle back when the landing looks to sketch.

Maybe these slip trailers might land at dedicated/specific landing sites where they have the risk tolerance for an unmanned, potentially uncontrolled super-heavy glider landing, but it's still high risk to anything on the ground on its flight path should the unmanned glider crash
