Thanks for the link. The thing is, we can only fly two trips between each SOAP, and to make visits to the UK worthwhile we fly frour trips over two days. The best flying is in the north, but it seems that all the engineering facilities are in the south. We would need to be able to land at the end of the day, take the sample, post it, enjoy the nightlife... wake up the next day, ring the company and get the results by 0730, 0830 at the latest. I'm just not sure that the UK postal service or even an independant courier can crack that sort of timescale, let alone ask the engineering company to work the night shift if they don't already.
Any other contacts from you knowledgeable types out there?
Appreciate your help in advance,
GM
