Delta can see that they won't get enough pilots in the future, hence they are trying new ideas to hopefully cover the flying that they have planned. Same goes for EVERYONE else, including AA/UAL/UPS/FedEx/SWA+++++.

If the flight schools can get these new electric trainers online soon enough, then the worst of the Pilot Shortage may be averted. If not, I think UAL/AA/DAL will have to hire kids of HS/college age and train them, just like the Mil does.
