Yep it was already a short term solution, also going to replace them with B727's
I actually thought they were nice, replaced a few DC-6B flight with the Convair 990. Nice and fast compared to the DC-6B and the load factor went up a lot using the Convair. It's nice to see that the game is modeled that passengers like speed and therefor prefer the Convair over the DC-6B. But the B727 will be much better, can't wait till my orders start coming in.
