First of all this will not work because then you will have 5 ships in the air for transport because every reg thinks they need their own transport.
Second with these regimental pilots you suggest, they will be under different regimental leaders while if you do transport it is very useful to be able to communicate with the other people who are doing transport (speaking from experience) plus battalion can just leave the flying to CE and not worry about it, with reg pilots this will be an completely different story.
And at last suggesting this will most likely kill our regiment and I don't see the point because we do our job just fine.
