the logistics of this seem hilarious and ridiculous, but i guess we're still in that stage with electric aircraft where nothing is too outlandish to be off the table:

Magpie Aviation’s concept uses one or more electric aircraft to act as a tractor plane towing a passenger (or cargo) aircraft using a long cable. The towed plane would have enough battery power for takeoff, landing and flying to alternate airports but not enough to fly the full distance on its own, as reported by AeroTime.

The lead plane would take on the bulk of the traction, and when its battery is depleted, it could hand off towing duties to another electric towing aircraft to extend the rear plane’s range. Magpie CEO Damon Vander Lind summarized to Aviation Week, “You get towed until you’ve depleted down to your reserve in the lead aircraft, and then you swap in another tow aircraft.”
