The total time is perhaps a little on the low side .. personally if I owned a 139, I'm not convinced I would be happy with 2300 hour Capt ....
Actually, I would probably go for a 6k plus Captain and a 3k plus FO, both with five years onshore relevant experience .. and even then I would be careful !
It all depends on if you are willing to pay for it. In this specific case, with this owner, I have my serious doubt!
JJ, IMHO I don't believe you should destinguish between ex mil and civ. trained, only what the rules says about min. vfr wx for t/o. It's the same minima no matter your background and experience. End of story. If the rules were broken, and the accident wouldn't have happend if the crew had followed the rules, then all I can say is: Too bad, you paid the ultimate price, but it was your own fault. The rules are there for a reason.
