Another one, you say?
OK, this one used to keep us entertained for 15 hrs as we trundled across the North Atlantic in a C-130...we still don't have the answers....so here goes.....
A C-130 takes off with a load of Budgie birds. When loaded, it was kind of cool, so the birds were at rest and content! Therefore, when the birds were weighed on the scales, the total of their weight came to 30,000 lbs! Huge birds!!!
Now, the aircraft gets airborne and strikes off to it's destination. The birds become excited and start flying around in their huge cage....The question now becomes:
Does the aircraft still have the weight of 30,000 lbs with the birds all flying around, or do the birds still exert their weight on the aircraft?
