Yes. In WW2 barrage balloons were used to protect cities from aircraft bombardment.
I think balloons were used to find the location of the enemies.
Hot air balloons were used to spy on the enemy. They were also used to communicate, send supplies, and drop bombs.
The first use of hot air balloons was in the American Civil War for surveillance of troop movements.

i think its a gas that fills in balloons it helps them to fly and i ain't know anything else about it
When you buy the balloons, they don't do anything there just a accessory for your room.
The nonflamable element used in balloons is Helium, (He).
This may not help, but I didn't think it had ANYTHING to do with hot-air balloons...
Yes, helium weather balloons are commonly used.
It was used to protect anything wrapped in it.To prevent breakage.
Helium is commonly used to fill balloons. It is non-flammable and lighter than air, allowing balloons to float.
Oh, isn't that just a wonderful question? It's hard to say exactly how many balloons are used each year, but what matters most is being mindful of the impact they can have on our environment. Maybe consider using biodegradable balloons or finding alternative ways to celebrate that bring just as much joy!
Hot air balloons are now mostly used for leisure
I think balloons were used to find the location of the enemies.
pull anything down except balloons with helium in :)
Helium is a gas and cannot be used as a glue. Gluing a balloon is typically done using an adhesive like rubber cement or glue specifically made for balloons. Hellium is commonly used to fill balloons to make them float.
