What were the balloons over London for in ww2?

Balloons were intended to defend against dive bombers flying at heights up to 5,000 feet (1,500 m), forcing them to fly higher and into the range of concentrated anti-aircraft fire: anti-aircraft guns could not traverse fast enough to attack aircraft flying at low altitude and high speed.

What were the little blimps for in ww2?

Both the Allies and Japan also used balloons during World War II. The Allies used barrage balloons (small blimps) to suspend aerial cables in the sky and foul enemy bombers.

What were all the blimps for on D Day?

barrage balloons
These were blimps in a sense but were known as barrage balloons. These blimps were tied by cables to ships during the invasion to prevent German air attacks. If a plane hit the cable the wing could be pulled off and it would crash.

What kind of gas did both Germany and Britain have to use in their observation balloons?

hydrogen gas
The balloons were fabric envelopes filled with hydrogen gas, whose flammable nature led to the destruction of hundreds of balloons on both sides. Observers manning these observation balloons frequently had to use a parachute to evacuate their balloon when it came under attack.

What gas filled barrage balloons?

hydrogen
A vital part of the UK air defences during the Second World War were barrage balloons. Large structures, about 19 metres long and eight metres in diameter, they were part-filled with hydrogen and deployed to altitudes of up to 5,000ft.

What did barrage balloons do in ww2?

Barrage balloons worked as both a passive and active means of aerial defense. Floating barrage balloons over a specific area prevented enemy aircraft from flying close enough to target the area from directly overhead with bombs or strafing fire.

The top of the balloon was filled with hydrogen, the bottom half was left empty, so when it was put up at a certain height it filled with natural air.

What happened to balloons when they were used in WW1?

Balloons lost a certain amount of hydrogen when flying so they had to be topped up every day at the sites. Balloons were held by cables which were fixed to winches on lorries. Cables were more important than the balloons as an aircraft had only to touch a cable and it would be destroyed straight away.
