At Papa Charlie, the Paragon Contech Contract
SASless: Do you, by chance, mean the Prakla Seismos contract in south western Iran. Yes, we did fool around with whitewashed stones at some of the camps but I don't remember the indident you mentioned - perhaps I was on time-off. If you were there you'll be very familiar with flying the Labo around and a cabin full of boxes of dynamite. Or when we operated in the marshes around Khorramshar and the improvised floating landing pads would float away as a result of the downwash on approach and you had to go chase them to land on, much to the consternation of the seimis crew who would have to wade through chest-deep water to get back to the seismic line.
If you were there at the end of that contract, you'll probably also remeber the CP buying the toilet from the German party leader for us to take to the next seismic contract which was a French company with the initials GBS. Very similar work but the food was fantastic.
