Icelandair did let the 421 on. They did not even charge us much. Now we need to get it to the north of Iceland. It is too big to fit in the wagon we have rented. Therefore, I am taking the bus, so I have some time.
We are testing the Dualem 421 out in a bunch of different places. (http://www.dualem.com). We are also trying the CMD mini-explorer (www.gfinstruments.cz) but that is a much smaller piece. In particular we are testing these at the lower Seyla churchyard.
