I have recently read that it was six EMB195s that were being returned to their lessors but had previously read it was just three, they are being returned to their lessors so it will be upto them as to where they finally end up, the rumours that they will go to Stobart are that just rumours especially from the Southend forum as I said they could end up anywhere once their leases are up with Flybe.
I wouldn't put Flybe and committed in one sentence and 'Project Blackbird' at the end if the day means sod all to Flybe, they just started the 'project' with the aim of getting subsidised operations at those airports you mentioned.
