The pressure on governments to monitor their borders is a hot topic. The European Border Guard is charged with monitoring and protecting its (and the EU’s) borders from people trafficking, smuggling, illegal immigration, arms smuggling, goods smuggling, combating terrorism as well as monitoring all sea, land and air security. It’s a big operation and the two ES15s are an important tool in carrying out this vital task in an efficient manner.
People don’t look up unless they are alerted. It’s obvious that the quieter the aircraft the less opportunity to alert those on the ground to the fact that they are being watched and monitored. Operating at 7,000 feet makes the ES15 impossible to hear and if it is spotted then the profile is that of a glider. The ES15 doesn’t attract attention which makes it ideal for this line of work.
