"Gulfstream has been involved with SAJF since June 2011, when a Gulfstream G450 became the first business jet to cross the Atlantic on a blend of the fuel. Since then, we've taken ever-greater steps in supporting sustainability, including securing a dedicated supply of SAJF for our corporate, demonstration and flight-test fleet."
