Probably the last big trick to be done on QZ, is getting a vehicle into the Index Chamber (or, at least, the room/ building prior to it.)
Hey, I think I made it in by a nose (or the folded-out flap of the nose)! It was at least 1/4" inside, or maybe a nostril hair. Now someone else will have to get a vehicle all the way inside and swordfly.

Thanks, to Duke and Termy for all this (FP). Gramps is not grumpy anymore.
