Bye Aerspace eFlyers Ordered By Quantum Air Another company is on board with the electric planes for Air Taxi services in the future. Quantum Air has now ordered twenty-two (22) eFlyer 4 (four seaters) and four (4) eFlyer 2 airplanes (two seaters). Quantum Air is a Los Angeles based Air Taxi service. Even though these new orders are in, there is no real timeline for when the planes are to be delivered. Knowing the stage that the eFlyer program is at, -critical design review-. If all goes according to plan, Bye Aerospace should have Federal Aviation Administration (FAA) FAR 23 type certification for the eFlyer 2 in 2021 and eFlyer 4 in 2022. This should give a much better idea as to a vague timeline.
