Prang One:
If an on the spot breath test reveals positive, another is taken and if that is positive then blood samples are taken for further examination. 5ml of blood are taken and divided into two, one for the Forensic Science laboratory and the other for private analysis, if the subject wishes.
Gas chromatography is used to find the quantity of Ethanol present. (I won't go into the proceedure). In a modern lab the sample is run on two separate machines operated by two separate officers to obtain total coroboration.
Once again all this post is for general info on proceedures and has little to do with the original thread...The chap was cleared ....close it.:D

It is rumoured, that the esteemed leader of Britannia Airways has a desire to sue the (esteemed) FAA for the (rumoured) £300,000 cost of this spurious delay.

Go for it Kevin!!!!!!!!

I wouldn't mind finding "The Sun" in the dock as well. Now that would be supporting your employees.

Bally,

Can you expand on that? £300K seems a lot, say £1k per pax. What elements go into this claim?

I must admit the £300,000 is a figure which I heard and didn't question. However, it's not just one load of passengers who are delayed, there are knock on effects. Plus the only way to recover a twelve hour delay quickly, if you have no spare aircraft is to sub-charter.

In full support of Sky 9 Take the Sun on put them in the Dock, At least they should write an article stating that the F/O was in the Clear and that the Error was with the testing Equipment.

Come On K.H. Support your staff have a go at the Sun !!!!!!!
