It is a fully owned subsidiary of El Al which uses the brand mainly for seasonal scheduled and charter services mostly to European destinations.  All of their flights are operated by El Al, as Sun d'Or's own license was suspended in 2011. Sde Dov Airport (Hebrew: שדה דב‎ ‎ , "lit."  Dov Field, Arabic: مطار سدي دوف‎ ‎ ), also known as Dov Hoz Airport (Hebrew: נמל התעופה דב הוז‎ ‎ , "Nemal HaTe'ufa Dov Hoz", Arabic: مطار دوف هوز‎ ‎ ) (IATA: SDV, ICAO: LLSD) is an airport located in Tel Aviv, Israel which mainly handles scheduled domestic flights to Eilat and Uvda (a.k.a. Ovda), northern Israel (Haifa and the Galilee), and the Golan Heights.  It is the largest airport in Tel Aviv proper, and the second largest in the area, after Ben Gurion International Airport on the outskirts of Lod.  The airport is named after Dov Hoz, one of the pioneers of Jewish aviation.  The airport is expected to close by the end of 2018 after an agreement was struck re-purposing the land which houses it for residential apartments.  Commercial flights will move to Ben Gurion Airport.  The airport is a focus city for Arkia Israel Airlines and Israir Airlines. Nevatim Israeli Air Force Base (Hebrew: בסיס נבטים‎ ‎ ) (IATA: VTM, ICAO: LLNV) , also Air Force Base 28, is an Israeli Air Force base located southeast of Be'er Sheva, near moshav Nevatim.  It was built as a rough runway in 1947 for the Sherut Avir, the air wing of the Haganah, and was named Malhata.  It was reopened in 1983 as a new modern airbase with two runways as the result of joint Israeli and US government funding as part of the IAF's redeployment out of its bases in the Sinai after it was returned to Egypt following the Camp David Accords.  Since 2003 the base has gradually received more squadrons of F-16s.  A third runway was built in the mid-2000s decade as part of a project to accommodate the transfer of military activities previously taking place at Ben Gurion Airport (Air Force Base 27) to Nevatim. Since 2001, Palestinian militants have launched thousands of rocket and mortar attacks on Israel from the Gaza Strip as part of the continuing Arab–Israeli conflict.  From 2004 to 2014, these attacks have killed 27 Israeli civilians, 5 foreign nationals, 5 IDF soldiers, and at least 11 Palestinians and injured more than 1900 people, but their main effect is their creation of widespread psychological trauma and disruption of daily life among the Israeli populace.  Medical studies in Sderot, the Israeli city closest to the Gaza Strip, have documented a post-traumatic stress disorder incidence among young children of almost 50%, as well as high rates of depression and miscarriage.  A public opinion poll conducted in March 2013 found that most Palestinians do not support firing rockets at Israel from the Gaza Strip.  Another poll conducted in September 2014 found that 80% of Palestinians support firing rockets against Israel if it does not allow unfettered access to Gaza.  These rocket attacks have caused flight cancellations at Ben Gurion airport.
