Basic English
N.A.S.A. says: Where do contrails form? Contrails are human-induced clouds that only form at very high altitudes (usually above 8 km - about 26,000 ft) where the air is extremely cold (less than -40°C). But now we see (with Airnav Radar) that this aircraft flies at 13.050 ft (about 4 km), so these not are contrails, but chemtrails!
**************
"Secondo definizione FAA ed in base ai documenti ufficiali N.A.S.A., una Contrail si forma generalmente sopra gli 8000 metri circa, a temperature minori di -40°C, e con umidità relative superiori o uguali al 70%. Noi, grazie all'utilizzo di strumentazione adeguata (Airnav Radar), abbiamo potuto verificare che un aereo rilasciante abbondanti scie, volava alla quota di 13.050 piedi, pari a 3977,64 metri. Dunque... quelle non sono scie di condensazione, ma scie chimiche! Alle nostre latitudini, infatti, è impossibile si generino scie di condensazione a quote tanto basse.
Also you have to consider it is just coming from off the coast where there is a higher humidity which can also help to induce contrails at a lower altitude.

It takes just the right conditions but it is completely possible. Also you look up the registration number D-AKNG it's a Germanwings A319 All you're seeing is condensed vapor out the engines it's impossible to have chemicals come out of the engines besides spent jet fuel.
