HERKMAN,
Ahh, the pogo stick, and the poly bag. Many a morning I've spent doing water seds, and trying to work out how to dispose of the results. Dakar in Senegal often attracted an audience, more than willing, to relieve me of the burden. RAF Germany was another matter, despite the words of hardship from the "linie's" at Wildenrath, none offered to make use of my samples. Usually dumped in the Houchin cable stowage bay. I agree though that water sed was an important part of "looking after your Albert", and having seen some real crud in the sample bag, made a point of doing the checks religiously. I assume IAF is Indian, not Israeli Air Force.
