Canook - Your info is a little skewed. Just got off the phone to management at Superior and here is the goss.
Yes they are sending one back at the end of October. Thats a sure thing. Then if they dont get the contract they are bidding on then they will "probably" send the second one back at the end of the lease period in December. That was always the case. They leased those two machines in the hope of a good fire season in the US but that didnt eventuate.
If next years fire season looks promising they will re-lease the two they are sending back, unless someone else has got them first.
Hope that info helps.
