Thanks, Warp. Do you think they still power it with Blau Gas? Expensive to produce and acquire. I don't know if there is a producer in the States, even. It has similar combustibility to propane so maybe you could substitute that. Although that is heavier than air and Blau gas was buoyancy neutral. Maybe they made the jump to methane which is LTA? I am not doubting it was designed to run on Blau gas, just wonder if it still does. Am glad to be enlightened. Need to see the Argus, I guess. One look would tell. Thanks for all you do for the company--and for us SH's, Warp. Warm regards, IndyJonesOhio
