While on a recent business trip I had some time to visit the CAF museum in Mesa, AZ. It’s a great little museum and I enjoyed poking through the planes (including a great B17) and buying a gift for my dad. A piston from a P-47 engine. How many of you can say you have one of those? 🙂

Getting to the airport wasn’t bad. We were fairly close and made it in just about half an hour. I had printed my boarding pass ahead of time and breezed into the security line where it all went slightly pear shaped.
After several days of tests I’ve gotten a couple of decent transmission holograms on VRP-M using a Coherent 315m.
This is the picture that I mentioned in my previous podcast. Susan took it around sunset and once we got home played around with it in Picture Publisher (yep, she still uses it).

It’s been a year since I wrote this post about the problems in New Orleans in the aftermath of hurricane Katrina.
I think it’s very relevant today as much of the nation thinks back to September 11, 2001.
At the time I hadn’t thought about the connection between the two events even though I was writing my comments on 9/11 but in light of our steadily eroding liberties as we travel the skies I have to wonder just how far things will go before we say "stop!"
The terrorists are winning and as a group we’re not doing enough to get our leaders to realize that the more restrictions they place on the the law-abiding citizenry, the more the terrorists achieve their aims of making us all afraid.
New Scientist is reporting that the FDA is testing some new hardware that locates flaws in rail lines using lasers.
The laser pulses create ultrasonic waves that travel through rails at high speed. This means the device can scan for cracks while being pulled along a rail track at up to 112 kilometres (70 miles) per hour – much faster than existing equipment. The machine identifies microscopic fractures by monitoring the strength of ultrasonic waves passing through a rail.
The lasers vaporise a very small amount of the top of the track as they simultaneously generate transsonic waves that can be detected by a microphone positioned ahead of and above the track. This is much improved over previous methods which limited the testing speed to 50 km/hr.
