The company stated the flight consumed about $5 worth of electricity, a figure highlighted against the backdrop of rising jet fuel prices, which averaged $3.50 per gallon for the week ending August 7, up 63% year-over-year.

The X1 is not intended for commercial passenger service. Instead, it serves as a full-scale flying laboratory to validate technologies for Heart Aerospace's planned production aircraft, the ES30. This upcoming model is a 30-seat hybrid-electric regional airliner designed to combine electric motors with a turboprop engine running on sustainable aviation fuel. The ES30 is projected to have an...
