According to Seattle Times, all spectators were able to hear was the plane's buzzing sound coming from its propellers.

The startup that made the test flight possible is Eviation and its electric plane is called Alice, which can carry as many as nine passengers and one or two pilots for a few hundred kilometers at 4.500 meters.

The electric aircraft is powered by over 21.500 Tesla-like batteries, which weigh in at 4 tons or half the plane's total weight.

Eviation CEO Greg Davis mentioned that the design of the aircraft that carried the demonstration flight in Moses Lake isn't the final one that the company will use for the commercially-available units, pointing that the battery tech still needs some improvement.

He said that "are the batteries on the prototype aircraft capable of propelling the certification aircraft, capable of providing sufficient energy? The answer is no, absolutely not."

"What we’ve just done is made aviation history. This is about changing the way that we fly. It’s about connecting communities in a sustainable way", he added.

Steve Crane, who piloted the prototype, stated that the plane "flew and handled wonderfully."

"The team did a great job, built a great airplane. It’s a fast airplane, very responsive. I couldn’t be happier."

The pilot pointed the fact that the engines of the plane are virtually silent, making it so that he only heard the other moving parts, such as the propellers.

"What’s next is actually producing an airplane for the marketplace", Davis said.

"This is an amazing achievement, but this is just a milestone in terms of where we’re headed", he continued.

Besides having different batteries, the final production model will also be featuring pressurized cabins.

When the production model will be ready to take off, the company can also seek FAA certification, which will mean that the plan is safe to be used for commercial flights.
