@catch 21
I see your point - but in that case why towing equipment which has been said many times to be very slow? Wouldn't you want to reach the other side ASAP? Or is it common to keep on surveying on route to another search side?
I am not claiming any conspiracy but it seems that it is quite unusual, indicating that as we all know there is probably more info we do not know about.
If they have found something it would be great in any case!
