The full-on launch base was still being built on Kilimanjaro, but smaller fields dotted the land all around it. We were taking some sort of scramjet back to the States. It was one of the new STOL ones, so we didn't need to use the old, miles-long runways; just pointed in an almost random direction and, with a strangely smooth lurch, we were in the air. As we banked around, still going fairly slowly in the local traffic airspace, our path paralleled that of some local hobbyist who was lifting off in an old Vought F4U Corsair-- nearly a hundred years old now-- and I thought someone should get a picture of the two of us in the air together. I had just a moment to wave to the Corsair pilot and give him a thumbs-up before our own pilot extended our fan-tail, opened the throttle, and pulled back on the stick. We went sharply vertical and, within seconds, the other plane, the base, and even Kilimanjaro itself were receding out of sight.
