If you spend a day somewhere, you can get absolutely nothing out of the ordinary. Alternatively, you can be somewhere for a short time and get a really lucky break. I was down in Hayward awaiting an unusual Airbus movement as I headed to something else and, in the short space of time I was there, someone else showed up. This was a Boeing 757 that has been converted for private charter use. I have actually come across this aircraft before but, when it showed up heading in to Oakland, I was rather pleased with my good fortune.
