"We're really excited to partner with [Blade] because they have the most operational real experience and can talk credibly about the opportunities and the benefits of flying aircraft in and out of cities," Beta founder Kyle Clark told CNBC. Blade gets the "opportunity to do flight paths that they presently are not doing with the capabilities of this aircraft," Clark added. "The EVA is really going to shine in complement to their existing helicopter fleet." EVAs, also known as eVTOLs, are electric vertical take off and landing aircraft that look like they're part helicopter, part plane. Last week, Clark's Vermont-based electric vertical aircraft maker struck a deal to sell at least 10 EVAs to United Parcel Service for testing on package delivery.
