I am not a defender of Malaysia Airlines but they operate over 100,000 flights in 2012. That $10 per flight is 1 million dollars. Malaysia Airlines has consistently lost money and is owned by the Malaysia government who was rumored to have wanted to sell. Of course in hindsight, it would have been wise to subscribe but this is what SWIFT does:
"Had the Swift system been upgraded to include the full package of applications, it could have sent information on engine performance, fuel consumption, speed, altitude and direction, regardless of whether the transponder and ACARS were working, he said."
This information can be downloaded on a USB drive once the plane is landed.
Engine performance - well Rolls Royce does that already
Fuel Consumption, speed, altitude and direction (transponder and ACARS).
Problems - that's the pilot's job to report.
From the point of view of the Board and CEO this service might have been redundant. They are hemorrhaging money (lost 130 million dollars in 2012) and this is not going to be a high priority in my opinion. Hindsight is 20/20.
