TOTD,
An S-61T on two engines is better than an S92 on two engines; or at least thats what the Yanks themselves think.
I don't fly them but as a mender who sometimes flys I can say I would rather have more engines than less, and it doesn't have to be better on two engines; just as good as!
New S-61T Helos for the US Government
Cheers now
