Air cargo has been a huge relief to transportation industry all over the world. If there is a package to be sent instantly, just give it to be sent via air mail and it will be received at the other end within a couple of hours. Unfortunately there are some limitations to what can be sent through air cargo. The things that are restricted to send are highly explosive and unstable substances that can undergo a reaction from air pressure. When the airplane takes off to the heights in the skies, the air pressure inside become pressing and can cause some disturbances.

If you are sending something that has nothing to be bothered by the air pressure, then praise the air cargo industry for speeding up the delivery. Air planes look tough on the ground, they are, no doubt about it. But when the air plane takes off, it is like a soap bubble that can burst from the slightest external or internal pressure. At the high speed it travels, the atmospheric pressure and air friction makes it look like the weakest thing. Unfortunately we have evidences in history that prove a plane blowing up because of the smallest leak.

The leaks occur in the hatches which become weak due to the wear and tear of being used. The more they are used, the weaker they get. Hatch cover ultrasonic tightness testing is now conducted to check the weak hatch covers of the air plane and also to learn about any holes that might have emerged. The entire body of the air craft is checked thoroughly for the leaks because zero tolerance has been defined against holes in any part of the jet.

Scanning with ultrasound is completely safe with zero percent risk factor. Since the ultrasound waves never change the chemical or physical properties of the object they come across, one can easily use the device without fearing damage. The waves also do not act as a conductor to pass electricity or create an electronic field. This means that if there are electric wires running through the floor or the ceiling of the cargo hatches, there is nothing to worry about electric short circuit because of the checking of tightness of hatch with ultrasound. This test has made the air cargo safe and reliable to a huge extent and now not only are the goods safe onboard, but the pilots and the crew are also safe.
