So now we are dropping shipping containers with wings out of the sky when things go south with the towing.

In order to make such a contingency safe, we'll need swathes of ground that are clear of any population so that these things can crash without collateral damage.

If you have a corridor of land that's void of population between your origin and destination, then you might as well, you know, lay down some tracks or tarmac and get rid of the whole flying business altogether.

Now, if you have a body of water between your points this might be a better suited plan I think.
