   With the wikipedia articles on jet aircraft, there is usually listed the   
   pounds-force thrust that is generated by each of the engines, which   
   along with the empty weight (or whatever additional weight you want to   
   add) can be used easily to calculate the thrust-to-weight ratio. Some   
   fighter aircraft achieve 1:1 but most commercial jets are somewhere   
   around 0.6 to 0.7, from what I can tell.   
      
   In the specs I was seeing for propeller aircraft, it seems what is   
   usually listed is weight-per-horsepower, or power loading. That is   
   interesting, but I was having trouble seeing how to compare the two.   
   Thrust is more intuitive to me one can see directly the ratio between   
   thrust lbf and weight lbs.
