Battery check.
You can buy a special spray for testing whether the smoke alarm reacts to smoke.
IMHO the best option for smoke alarms is to have them mains powered. However this involves fitting fire resistant cable which is expensive compared to normal cable. The reason fire resistant cable is used is it means smoke alarm will still be powered. Mains powered smoke alarms also have a battery backup.

As a follow up to my previous post....
The smoke alarm that failed was a few years old. It's battery (9 volt) was replaced Jan 1st, and the detector was tested at that time. I'm beginning to wonder if the "test" button on the detector actually tests the ability to detect smoke, or if it is just a battery check.
The newer smoke detectors use a built in lithium battery that they claim lasts for 10 years. After 10 years you take it down, flip a switch to discharge the battery and toss it in the trash.
When I see photos of the CH 47, I am reminded of my ride in one from Houston to Harlingen (the old CAF HQ facility). It was a 5 hour car ride, the Chinook took over 6 hours. We got off feeling like we had spent as many hours in a Kitchen Aid bowl mixer. We were beat, but our work was just beginning. We had to unload our support equipment and set up to receive 3 F-4 Phantoms, turn them and send them back to Ellington. Then we found our hotel rooms were booked at a State Legislators motel. We discovered it was a motel front for a prostitution and drug operation. We spent a few hours finding another hotel after complaining to our supervisors at Ellington.
And the view out back isn't too shabby either.................... This ended up being a test run because the sky closed up on me. I was concerned about keeping that much granite wet without the help of my assistant. It'll be much tougher with the sun out and some wind!
My second 50TB Drobo 5D will arrive on Thursday. Configuration and data back up at HQ went seamlessly. I'm using "Hedge" to facilitate file transfer/back up and have been having a running dialogue with the guy who designed it and runs the company. Seems that they don't have anyone moving the amount of data I do, so I'm kind of a Beta tester for them. The first block of files I backed up to the initial 50TB 5D was 17TB. Because "Hedge" is a program that prepares each file and verifies the complete integrity of the back up/transfer, it takes a while, five days in this first case, but it seems very trustworthy.
The beauty of HQ, aside from the obvious , is that I can initiate an intensive task like that, or a big video rendering project, and just leave it to do what it needs to do. I find that intensive tasks run more smoothly if you aren't working on that computer while they're running, less errors occur.

Yes, 5 days for 17TB may sound a long time. However, experience with my own rather modest data set indicates that your right on the money. My 2TB - on rather mid-powered machinery - takes just over 24hrs. Anything substantially quicker is likely not checking the data integrity properly IMHO. Love the way that all this video stuff has turned you into the data storage equivalent of an Auric Goldfinger. You could run a small country on 50TB
They recruit every now and again Zane. A lot of the time they are looking for an ex Air Force photographer who is experienced flying and working in the back seat of a fast jet.

That is a Kitfox Mk3. Amateur built airplane, "kit".

Interesting job posting by Lockmart for an aerial photographer!
Looking for some info on Davis–Monthan Air Force Base in Tucson, AZ. I was in Tucson last year and was surprised at how busy that base was. Many takeoffs and landings. I will be back there late July. Anyone know if there are good (and safe) vantage points to get some shots there? I will be prepared this time. Thanks for any and all info. PM me if you think this is not appropriate for this topic.

When I was stationed there in early '67, a Phantom went in a couple hundred yards from my barracks. The pilot stayed in to keep it away from an even closer barracks; the co-pilot ejected at the last possible second.
