Ufo over Amsterdam

Watch in Full screen please. OK, so I saw one again, it is a different angle andmy iphone was out of battery so it just stopped filming. I walked past the window with the phone in my hand to charge it and this thing appeared out of nowhere. After my phone went dead I saw it take of at enormous speeds. Strait up and it just disappeared. I live next to Schiphol airport and most definitely know the difference between planes and non planes. This is not an airplane. Since the first time I saw an ufo I don't stop looking at the sky anymore and I think it paid off.
