24th April 2015, a SyAAF MiG-23ML operating from Khelkhleh AB -serial is still unknown- and piloted by Captain Hasan Muhammad Mahmoud was shot down by ISIS' fire and crashed near Bir Qasab area to the North East of the airfield.
Pilot was KIA due to serious injuries.
Yesterday, 29th Jan. 2015, a SyAAF MiG-21bis -serial is still unknown- operating from Khelekhleh AFB and piloted by Col. Medhat Othman Kherallah "العقيد مدحت عثمان خيرالله" was downed over Tal Osheheb to the east of the said airbase -as reported by pro-regime personnel- or Bir Qassab to the south of Damascus and around 30km to the north east from Khelekhleh AFB -as reported by media of ISIS- which sounds more plausible.
Whether the bis was downed over Tal Osheheb which is located 8km exactly at the same axis of the east-west runway of Khelekhleh airbase, this brings to mind that ISIS units located successfully their AA guns/MANPADS at the route of landing of fighters at this airbase.
