Received the Airborne and have started assembly. The Drive Side cup won't start though the threads look perfectly OK.
Are you screwing it in the right way? It is ISO left hand thread. The fact that it is a Ti BB shouldn't make it harder to screw in the cups unless the threads are munged. You'll need anti-seize with aluminum cups going into Ti.
The Airborne has a BRC Profile Designs fork on it and it looked like it was left out in the sun for a long time and the finish was flaking off of it.. This didn't give me a great deal of confidence in it so I ordered a new identical fork. This will mean I have to remove the lower fork race and install it on the new fork. These fork headset bearings were made by Airborne and they feel like new so I'm confident in the rest of the bike as well. Oh, wait, some of the nutcases here think that the titanium is "worn out" and suffering from metal fatigue. Without knowing a single thing about the history of the bike mind you. This is a demonstration of the quality of thinking here.

Oh, wait, some of the nutcases think you got into the way-back machine and bought a discount Ti bike (with a documented history of failures) with a 1" steerer fork for no apparent reason except maybe some compulsive disorder. Now you're going to end up with a 21 year old POS with a NOS Profile fork -- and you mis-ordered your crank, so that has to go back. More work to get a simple part for an ISO threaded BB bike that will be worth whatever parts you put on it.

One hopes you don't bend the crown bearing seat taking that off and have to go rummaging around for a 1" replacement. This is like Mr. Magoo does bikes -- humorous but at the same time scary.
