So with all this time to think about it , we as a large group of professional pilots
don't know what the fire crew should have done . Don't you think it's a bit harsh to condemn them when they 1) are not familiar with the workings of helicopters and 2) had minutes to think about what to do .
I personally think that foam all over the aircraft and floor would have done little to stop a fuel fire and may have effectively lubricated the rough floor and made the aircraft spin even faster ... But who knows .
On first look I do like the idea of auto spool down to FI after x number of fast spins , especially if you could override it if you wanted to keep power .
