This again just like the enthusiastic amateur crash investigation threads.
You don't even know what is relevant!
IFF u/s you say.
Don't think anybody is getting airborne without mode 4 at that point. Get shot down by red crown pretty quick methinks.
IFF on off broken fixed who cares! Why would that be relevant? Do you think that any of the other helicopters even had the ability to see an IFF? Or had TCAS. Or were even radiating!?
Radar not functioning. Hmm. Really?
An aircraft that has only one purpose which is to be an airborne radar and they were going flying without the radar?
I think not. Did it perhaps have limited functionality?
This might seem like a strange question to someone with no knowledge of maritime ops.
Let's assume for the sake of argument that the bagger was getting airborne without a serviceable radar. For fun maybe.
How exactly do you think that this would affect the collision? What do you think that radar does/is good for?
An aircraft with u/s JTIDS, u/s radar is no more dangerous than all the other aircraft in the air that day not fitted with JTIDS or radar....
