That's the old AlphaSim XB-35. Like a lot of older FS2002 aircraft, it makes a great AI in FS9. I've got them showing up at quite a few Air Force bases that I've done AI for.
I wish there was a newer one for FS9. The XB-35 was quite the interesting aircraft that just took too long to develop and was canceled.
The MATS Connie is the FSDezigns L-049 that I converted to AI by using the CalClassic's AI L-749 flight model and plugging in the L-049 contact points and lights section. I had so many paints for the L-049 that it replaced a lot of the CC AI L-749s in the AI traffic. A wee bit harder on the frames, but it looks so good in FS.
