Back to the thread. Atlas had four 400F conversion slots but it let them go. It couldn't complete financing on the 800F order with the increased debt load. Today
Ummm ... that was not the reason. The -400 conversions are just too expensive if you don't own the airframe or lease already. The cost to purchase the airframe, coupled with the cost of the conversion, could not be amortized in the life left on the airframes of any of the available passenger -400s. So, since they would not be able to make any money on the conversion, Atlas passed on their slots. That decsion was made well before the announcement of the -8F purchases. Who knows if financing played a part. It sure could have, but that was also during the regime change so who knows.
BTW - the company web-site categorically denies any new aircraft coming to the current Polar fleet.
