Interesting I was thinking last night about how long this is taking. Seems long yet on the other hand I can see the value of the testing and a final independent review. It would seem to me to be a positive way for a entity such as the TSA to keep things on the up and up. I imagine there is a lonf distance between the folks that test, those that field a new product and the branch that pays for everything. I can imagine in the past old Uncle Clive could get a readiness on what ever he through together and the government was then on the hook for the contract. This way we know and they know the sniffer is the real deal and it works on x,y and z.
Here's another huge factor in why it's taken years- http://thehive.modbee.com/node/22087 TSA is a travesty IMO-and very fortunate to date. They absolutely need get it right this time with ETD
