In the operation of blimps one thing that is extremely important is making sure the gas does not escape. If the gas escapes from a lighter-than-air aircraft it will slowly float back to the ground. If it leaks out fast or punctures it will fall to the ground rapidly; if you are in it you will die. Dying is not good.

As we create balloon, blimps and military high-tech dirigibles and ask them to perform at higher and higher altitudes we will need to maintain stronger materials in the manufacturing of these lighter-than-air craft. There have been balloons, which have gone around the world and we have weather balloons, which resemble UFOs gathering important data about the winds aloft and our atmosphere. We have low and high altitude airborne communication stations and cell towers which operate out of balloons. We have aerostats or tethered balloons, which patrol our borders for a bird
