Boeing, NASA, and German Aerospace Center DLR have commenced flight tests on Thursday with a MAX 10 and Douglas DC-8 to study the effects of burning sustainable aviation fuels (SAF) on contrail formation and non-carbon emissions. Testing should demonstrate if there are any side effects from using SAF.

During the test flight, NASA’s DC-8 Airborne Science Lab was trailing the MAX 10 at some distance and taking measurements from the exhaust gasses. The Boeing was using 100 percent SAF on one CFM LEAP-1B engine and conventional kerosene on the other the check for any differences.
