   That may very very well be the case.   
      
   Maybe it has something to do with operating deep freezing equipment   
   near ordinary humans (passengers, various personell), and it has   
   something to do with the tendency of H2 to diffuse out of most   
   containers, over short time? And maybe it has something to do   
   with the fact that airlines tend to fly at constant speed over   
   their range, instead of explosively accellerating for the first   
   few minutes of flight?
