fuel quite early.  Testing by measuring the speed at which the airplane
stalled (related to the airplanes weight) reassured them that the fuel was
still (or again) in the tanks!

I think I read about it.
As I understood it, the problem was that in bad weather due to the
airplane«s movement, the fuel occasionally flowed backwards from some kind
of collecting tank back to the source tank.  Problem was that the sensor
they used could not differ between forward and backward...
