Some of the earliest experiments in aerial refueling took place in the 1920s; two slow-flying aircraft flew in formation, with a hose run down from a hand-held fuel tank on one aircraft and placed into the usual fuel filler of the other.

I still think that valuable close-ups of tornadoes could be conducted by slow-flying aircraft, with a pilot and a well-equipped meteorologist.

Although the United States has excellent air defenses against a conventional military attack, both slow-flying remote-controlled aircraft and terrain-hugging cruise missiles present a formidable challenge.

Work on the SB-2 Pelikan, a special "slow-flying" aircraft, commenced in the winter of 1941.

They attempted to warn the aircraft, but the MiGs caught up with the slow-flying aircraft.

He flew throughout the Battle of Britain, when his unit was assigned to escort Junkers Ju-87 Stukas (dive bombers), very slow-flying aircraft.

Any slow-flying aircraft would be shot to pieces before it could even land, and even if it could land, its troops would be cut up the minute they were on the ground.

The film makers had to devise light, slow-flying aircraft that could transport heavy camera equipment at goose-determined speed.

In the hands of a trained man, these were deadly weapons against a slow-flying, unarmoured aircraft such as the jet Ranger.

The gun can destroy lightly armored vehicles and aerial targets (such as helicopters and slow-flying aircraft).
