On November 22 Air Tanker 137 made the first drop by a Boeing 737 on an active fire. It occurred in the Hunter region of New South Wales, Australia.
In these photos the aircraft was dropping gel, which clings to the vegetation and retains the moisture.
Coulson completed the conversion of the 737 a few months ago and it is now working on a contract with the New South Wales Rural Fire Service during their summer. Nicknamed “Gaia”, it arrived at Richmond RAAF Base near Sydney November 11 after a multi-day trip across the equator. It will be primarily based at the RAAF Base along with three other large air tankers from North America — a C-130Q (T-134), and two RJ85s (T-165 and T-166). Two other large air tankers will be based in Victoria at Avalon Airport in Melbourne, a C-130Q (T-131), and an RJ85 (T-163).
The 737 Large Air Tanker ‘Gaia’ has been in action in the Hunter this afternoon – the first time this kind of plane has been used to fight a fire anywhere in the world. It’s provided valuable support to firefighters on the ground. #NSWRFS #nswfires #avgeek pic.twitter.com/qHnbcddFpe

Going by the coordinates on the images, the fire T-137 dropped on was very close to the Kurri Kurri Hospital southwest of Heddon Greta. The NSW RFS reported at 8:14 p.m. local time on November 22 that firefighters assisted by aircraft had slowed the spread of the fire. They estimated it had burned 61 hectares (151 acres).
