There are some nice images there, Brian.
Your shuttle images remind me of a story. In 1978 I lived a few miles from Ellington Air Force Base in Houston. On a Sunday in March or April of that year, the first space shuttle (Enterprise) flew right over our house and landed at Ellington atop a 747, and the Air Force opened the base to the public for the day. It was a very chilly day in Houston, and my wife and I bundled up our infant son and headed out to Ellington.
We parked about half a mile from where the shuttle was parked and walked towards it, I snapping pictures with a 35mm SLR. About 1/4 mile away I stopped to change film, then we proceeded to walk right onto the runway and up under the shuttle and 747. We were allowed to kick the 747's tires if we wanted, basically no restrictions. I took the full 36 exposures standing right beside and under the 747, and had to stop there because I didn't have another roll of film.
Upon returning home, I started to rewind the film, and discovered to my horror that the roll hadn't caught on the take-up spool, and I had nothing but the few images from the first roll, from a distance. Plus the memories, of course.
After that, I watched the rewind crank every time I cocked the shutter on that camera to make sure the film was advancing.
