Hi Frank, if you really want to personally take the dewar with you, here are my 2 cts (it is from a few years back, we send the dewars now by fedex): Just tossing the dewar on the check-in belt is not a good idea. It is a roulette with ever increasing odds that the dewar will not enter the plane

36% solvent sounds too low. Most protein crystals are at ~50%. On the other hand, if you assume one molecule, your solvent content jumps to 68% - not unheard of, but somewhat high for 1.7A resolution dataset. But you have a good MR solution, just try to refine/rebuild and see what you have in
