As I am familiar with LYBE, at the very end of the 30L there is ravine. No more strip, only grass (ground) but like a ravine (continuous downslope), because of the motorway that is connecting airport with highway. So they didn't take off - they where held by ground effect in the air after the tail strike and nose pull up. They only took off right before highway, approx. 6m above passing cars. So, ravine saved the aircraft. Also in left turn they were too low above suburbs (about 150 meters maximum). Lucky for them they were using 30L with only highway ahead, not any single obstacle. Everything can be seen on the video that passenger recorded, if you look closely.
If the ground was level now we be talking about worst air disaster for after 50 years in Balkans.
