Welcome
Bulent737. Nice to have new contributors to this forum, I guess there is lots of traffic high and low above Istanbul.
ContrailsUK I also experience this kind of effects more often recently. Contrails on lower levels and no contrails higher. Maybe it's something related to this season - spring?
Some new pics, from last few sunny days:
2008-04-14
Contrails were forming in FL330, but no contrails above FL370
17:53 UL29, flying high and no contrails
B747-400 B-2471 Air China CCA931 ZBAA-EDDF
19:15 UN858, at FL330 and nice contrails
B777-300 F-GSQA Air France AFR112 LFPG-ZSPD
19:19, at UL741(KRAKI-DUKAT) heading East - an interesting IL-76
IL-76 Gomelavia?
Not sure about airline. I guess it's Gomelavia, but it could be other companies as well. It flew from Kaliningrad, or somethere further from west like Denmark, Northern Germany? Maybe someone can help with exact identification of this one?

On this day contrails were forming on all altitudes, but thin cirrus layer at high altitude blocked the view. Only few pics I can show:
