What You'll Learn
The Blue Angels' use of jet fuel
The Blue Angels, formally known as the US Navy Flight Demonstration Squadron, are a flight demonstration squadron of the US Navy. The Blue Angels use jet fuel for their performances, which has raised concerns about pollution and fossil fuel consumption. Each Blue Angel-type jet consumes approximately 1,300 gallons of jet fuel per hour, with six fighters in each group. This results in significant fuel usage and contributes to climate-changing carbon dioxide emissions.
The Blue Angels' jet fuel consumption has been estimated to be more than 1,200 gallons per hour for six jets, leading to high fuel costs and environmental concerns. During a 30-minute round trip to and from Minneapolis, for instance, each jet burned about 500 gallons of fuel. The Blue Angels have also experimented with biofuel blends, flying with a fifty-fifty blend of conventional JP-5 jet fuel and camelina-based biofuel in 2011.
The Blue Angels' performances often involve low-flying jets, which can be a source of noise pollution and cause distress to some individuals. Additionally, the use of jet fuel results in the emission of particulates, which are microscopic toxic pellets that can pose health risks, especially in aviation emissions due to their small size. These particulates can enter the lungs and bloodstream, causing cardiovascular and nervous system issues.
Additionally, the Blue Angels have been observed releasing fuel during maneuvers, which has raised concerns about environmental impact. While some argue that this is condensation or smoke generated from linseed oil, others claim it is fuel coming from dump nozzles. Fuel dumping typically occurs during emergency situations to reduce weight at landing, but it is not a common practice during performances.

The carbon dioxide emissions from their jets
The Blue Angels are a team of jets that perform at military and non-military airfields and remote show sites. They often perform at major U.S. cities and capitals, and their shows include a range of complex maneuvers. The Blue Angels currently fly the Boeing F/A-18 Super Hornet, which replaced the McDonnell Douglas F/A-18 Hornet in 2020.
The Blue Angels' jets produce a significant amount of carbon dioxide emissions. Each Blue Angel jet consumes 1,300 gallons of jet fuel per hour, and with six fighters in each group, that amounts to 18,200 gallons of jet fuel burned per hour. This results in the release of a substantial quantity of CO2 into the atmosphere.
For example, during a 40-minute flyover, the Blue Angels' jets would burn approximately 12,133 gallons of jet fuel. Considering that each kilogram of burnt jet fuel releases 3.16 kilograms of CO2, this particular flyover would emit about 118 metric tons of CO2. This is equivalent to the amount of CO2 produced by a car being driven 292,720 miles.
The Blue Angels' emissions have raised concerns among environmental scientists and researchers. According to Keith Bein, a researcher with the UC Davis Air Quality Research Center, the jets emit approximately 825,600 pounds of carbon dioxide during Fleet Week. This is comparable to driving from San Francisco to Atlanta 375 times in an average car. While Bein acknowledges that this emission is smaller than what thousands of vehicles in a city like San Francisco would produce, it still contributes to global warming and climate change.
The Blue Angels' shows have also been criticized for creating noise pollution and causing distress to residents, especially in cities like New York with traumatic memories of 9/11. The jets' low-flying maneuvers, generating more than 20,000 pounds of thrust, create ground-shaking roars and can trigger unsettling memories for some individuals.

The impact of their air shows on the environment
The Blue Angels' air shows have been the subject of controversy due to their environmental impact. The air shows involve the use of jet fuel, which results in the emission of significant amounts of carbon dioxide (CO2) and other pollutants into the atmosphere.
Each Blue Angel jet consumes approximately 1,300 gallons of jet fuel per hour, and during a 40-minute flyover, they can burn over 12,000 gallons of fuel. This fuel consumption leads to the release of thousands of pounds of climate-changing CO2. For example, during Fleet Week, the Blue Angels jets emit approximately 825,600 pounds of CO2, equivalent to driving from San Francisco to Atlanta 375 times in an average car.
In addition to CO2 emissions, the Blue Angels' jets also produce particulate matter, which are microscopic toxic pellets that result from the combustion of jet fuel. These particles can pose a risk to human health, as they can enter the lungs and bloodstream, causing cardiovascular and nervous system issues. The low-flying nature of the jets during air shows can also create ground-shaking noise and disturbances, impacting residents' calm and peace, especially in densely populated areas.
The environmental impact of the Blue Angels' air shows has led to criticism and attempts to ban these events.
