Scared for residents after hearing a sonic boom over Hanover and the German region of Ostwestfalen-Lippe. Two aircraft of the German Air Force (Luftwaffe) of the Quick Reaction Alert Team took off from Laage on Monday around 12.30:XNUMX p.m. to check an aircraft from Mykonos bound for Amsterdam without radio contact. Because there was no radio contact when entering German airspace, the alarm was immediately raised.
Radio contact with the Transavia aircraft Boeing 727, which was at an altitude of 12 kilometers, was restored when the pilot noticed the air force south of Munster that signs were being made. According to the German air force, contact with Maastricht was then restored and the Eurofighters flew to home base around 13.00:XNUMX.
Dutch F-16s were also ready to deploy, but did not have to take action. The passenger plane has now landed safely in Amsterdam. According to a Transavia spokesperson, the radio was accidentally switched off.
A sonic boom, such as the "sonic boom" sound produced by an airplane breaking through the sound wall, is so loud because it is sound waves traveling through the air faster than the speed of sound.
Sound waves normally travel through the air as pressure waves traveling at the speed of sound of about 340 meters per second (or about 1230 kilometers per hour). But when an object moves through the air faster than this speed, the pressure waves build up in front of the object and form a shock wave that extends like a cone behind the object. This is called a “Mach cone”.
When this shock wave reaches the ground, it bounces back into the sky as an intense surge of pressure, which we hear as a loud bang. The bang is so loud because the pressure of the shock wave is much higher than that of ordinary sound waves, and the pressure wave contains a large amount of energy that spreads very quickly and covers a large area.
In short, the sonic boom is so loud because it is a shock wave that spreads through the air at a speed higher than the speed of sound, and this shock wave contains a large amount of energy that spreads quickly and covers a large area, making the sound very loud is.
