The dream of supersonic air travel is no longer a vision of the past. On January 28, 2024, Boom Supersonic’s XB-1 demonstrator aircraft successfully broke the sound barrier, marking a historic achievement in aviation. This marks the first time an independently developed supersonic jet has achieved such a feat.

Meanwhile, NASA is also preparing to test its X-59 aircraft, further cementing the return of supersonic aviation. If these trials succeed, supersonic passenger flights could soon become a reality—potentially at affordable prices, revolutionizing air travel worldwide.

The Historic Boom XB-1 Supersonic Flight

On January 28, 2024, at 7:45 AM local time, Boom Supersonic’s XB-1 aircraft took off from Mojave Air and Space Port to conduct its supersonic test flight. The primary goal: breaking the sound barrier by reaching speeds of Mach 1.1 (approximately 844 mph or 1,358 km/h).

This milestone follows 11 successful test flights conducted since March 2024, where the XB-1 already approached Mach 0.95—just below supersonic speed.

During the flight, piloted by Chief Test Pilot Triston “Geppetto” Brandenburg, the XB-1:

  • Reached a maximum altitude of 35,000 feet
  • Achieved a peak velocity of Mach 1.122 (750 mph or 1,207 km/h)
  • Broke the sound barrier within 12 minutes of takeoff

This test was live-streamed, capturing a historic moment in modern aviation. 25 engineers in the mission control center meticulously analyzed real-time flight data, ensuring the aircraft performed as expected.

Decades After Concorde: The Return of Supersonic Travel

The last time the world saw a commercial supersonic passenger aircraft in action was over two decades ago when the Concorde retired in November 2003. Concorde, capable of flying at Mach 2.04 (1,354 mph or 2,180 km/h), revolutionized air travel but was ultimately phased out due to high operating costs, environmental concerns, and limited commercial viability.

Now, Boom Supersonic aims to revive and improve supersonic flight by developing an economical and sustainable alternative.

Boom Supersonic’s Vision: The Overture Aircraft

Boom Supersonic isn’t stopping with the XB-1 test flights. Their ultimate goal is the Boom Overture, a next-generation supersonic airliner set to reshape international travel.

Key Features of Overture:

  • Speed: Mach 1.7 (approximately 1,304 mph or 2,100 km/h)
  • Passenger Capacity: 64–80 passengers
  • Flight Range: 4,250 nautical miles
  • Sustainability: Designed to operate on 100% sustainable aviation fuel (SAF)

Boom plans to launch Overture’s first commercial flights before 2030, offering supersonic travel at competitive prices.

Supersonic Flights for Just $100?

Boom Supersonic’s ambitious goal is to make supersonic air travel accessible to all. CEO Blake Scholl has previously stated that the company aims to provide four-hour global flights for just $100.

This vision is based on enhanced fuel efficiency, streamlined design, and advanced aerodynamics—all aimed at reducing operational costs and environmental impact.

Major Airlines Already Investing in Supersonic Travel

Boom Supersonic has already secured 130 orders and pre-orders from major airlines, including:

  • American Airlines
  • United Airlines
  • Japan Airlines

These companies recognize the huge market potential of supersonic travel, particularly for long-haul flights.

Challenges & Future Prospects of Supersonic Flight

While Boom Supersonic’s achievements are promising, there are several key challenges that must be addressed before supersonic flights become mainstream:

1. Noise Regulations & Sonic Booms

One of the biggest hurdles is overcoming noise pollution caused by sonic booms—the loud sound generated when an aircraft exceeds the speed of sound. NASA’s X-59 project aims to develop “quiet supersonic technology”, which could help ease these restrictions.

2. Environmental Concerns & Fuel Efficiency

Supersonic aircraft require significant fuel consumption, raising concerns about carbon emissions. However, advancements in sustainable aviation fuels (SAF) and more efficient engines could help mitigate environmental impacts.

3. Infrastructure & Cost Efficiency

Building an economic model that supports affordable supersonic flights remains a challenge. Ticket prices must be competitive to attract commercial passengers, and airports need to be equipped for supersonic operations.
