[9] The company identified its first customer as United Therapeutics, which under founder and CEO Martine Rothblatt was looking for efficient transportation methods for organs intended for human transplant.

[11][12] On May 23, 2018, the company made the first tethered flight of its original 4,000 lb (1,800 kg) Ava XC eight motor, eight propeller battery-operated proof of concept aircraft.

[18] In April, Blade Urban Air Mobility made a commitment to purchase up to 20 ALIA aircraft, becoming BETA's first passenger service company.

[22] The company announced on January 31, 2022, that it had won a U.S. Army contract to support flight testing of its ALIA electric vertical takeoff and landing aircraft.

Initially, Army engineers and Beta's team would evaluate how ALIA might best be applied to specific missions by measuring its range, altitude, endurance, and payload limits.

[28] In December 2022, an ALIA completed another test flight after traveling 876 miles to UPS Worldport, where its founder was met by U.S. Secretary of Transportation Pete Buttigieg.

[29] The same month, the company completed a FAA-sponsored 50-ft battery drop test with the National Institute of Aviation Research as part of crashworthiness determination for the eVTOL industry.

[32] In March 2023, the company sought FAA certification for a conventional take-off and landing (CTOL) variant of its ALIA aircraft, dubbed the CX300, and had received orders for the new product from Bristow, Air New Zealand, and United Therapeutics.

[38] In September 2024, the U.S. Department of Health and Human Services agreed a $20 million contract with the company to install its chargers at 22 sites across the East and Gulf coasts.

[43] BETA was granted a multipurpose special airworthiness certificate by the FAA for its first CX300 production aircraft which then performed its maiden test flight with CEO Kyle Clark at the helm.

[44] eVTOL aircraft can take off and land without the use of a runway, allowing smaller loads to be delivered directly to recipients,[45] whereas eCTOL require conventional, runway-dependent operations.
