Hi all...here is the UNOFFICIAL REPORT...but pretty reliable..While on descent to Jogjakarta GA 421 was flying in severe thunderstorms.On passing FL230 both engines flamed out.There were 4 attempts to restart the engines all unsucessfull and one attempt at starting the APU also to no avail.Then they lost their standby power (so much for 30mins)...while still IMC.They eventually broke cloud at 8000" and started looking for a field..decided to land on that river and was able to make one visual inspection..
before putting her down.
If this is so my congrats to the crew on ajob well done..
