Pakistan Air Force carried out its routine ‘High Mark’ exercise involving several air-crafts on the motorway. It should be noted that these exercises are held on timely intervals and motorway is closed for the entirety of this drill for the safety of civilians.
Sources have reported that safety barriers on the motorway were in the process of being removed from past 2 weeks. Apparently, ‘High Mark’ is one of the most comprehensive exercise arranged by Pakistan Air Force (PAF), which requires months of preparation and is held every 5 years. Here it should be mentioned that the last exercise was held in 2010.
According to DAWN; due to the closure of airspace, Pakistan International Airline (PIA) flights from Islamabad to Gilgit and Skardu were also cancelled. And more importantly a Notice to Airmen (NOTAMS) was issued three days ago, which carried the information about the airspace closure at different times on September 21,22 and 24 due to these exercises. Furthermore, the closure of M1 and M2 at multiple points was announced lately by National Highways and Motorway Police (NHMP). Sources have reported this announcement of motorway closure was associated to ‘construction work’.
