1.   An aerial tanker could be seen refueling a fighter jet overhead on Saturday.

2.   A third of the aircraft requested, for example, are aerial tankers, needed to refuel the waves of fighters and bombers conducting raids into Yugoslavia.

3.   British aerial refueling tankers have serviced U.S. Navy jets, and British planes have flown reconnaissance missions.

4.   The Air Force has also deployed dozens of aerial refueling tankers and transport aircraft around the region, the officials said.

5.   They also developed fluorescents for the fire retardants that aerial tankers drop on forest fires, allowing the next plane to know where its load is not needed.

6.   Three other models were tested by having aerial tankers pray their wings with water as they flew in formation at high altitude to simulate icing conditions.

7.   A helicopter, three aerial tankers and a lead plane also aided the effort, park officials said.

8.   That, in turn, would require aerial tanker flights.
