Tracing Planes above the Netherlands

My parents went for a trip to Indonesia. A nice site has been created: geluidsnet.nl where planes can be spotted above Netherlands.

Their plane took off around 11:20 .

11:25 North of Amsterdam

 

11:35 Above Almere

 

11:39 Above the Veluwe

 

11:48 Somewhere above Germany

 

11:52 Somewhere further above Germany, just before the radar couldn't spot their plane anylonger
