Narrative:
Ukraine International Airlines flight 752, a Boeing 737-800, crashed near Sabashahr, 7 minutes after takeoff from Tehran Imam Khomeini International Airport, Iran. Al 167 passengers and nine crew members on board were killed.
The Boeing 737-800, registration UR-PSR, had landed on schedule at 00:57 hours local time at Tehran. The return leg back to Kiev was due to depart at 05:15 local time (01:45 UTC).

In the meantime, around 02:15 hours local time in Iran, numerous ballistic missiles were fired from Iran towards U.S. bases in Iraq in response to the killing of Major General Qasem Soleimani by a United States drone strike.
As a result this military operation changed the alertness level of Iran’s air defense. At approximately 04:00 the military sector informed the civil sector of the country’s Airspace Control that only the flights already detected and cleared for flight operations by the defense network could be permitted to start up. This would ensure the correct identification of civil flights by the defense network and avoiding targeting them by mistake.

At 05:49 the doors were closed and the aircraft was ready to depart. Two minuts later the flight requested the to start up the engines.

After contacting the Area Control Center, the ATC unit requested clearance for the Ukrainian flight at 05:52. The Area Control Center forwarded the request for flight PS752 to the Air Defense Coordination Center, which subsequently issued the clearance accordingly.

The aircraft then taxied to runway 29R and commenced the takeoff roll at 06:11. After takeoff the flight contacted Mehrabad Radar and was cleared to climb to FL260 and turn right after reaching 6000 feet, heading direct to the PAROT reporting point.
As the aircraft was climbing after departure, it appeared on the air defense system. However, a wrong initialisation procedure of the system’s north alignment had induced a 107-degree error in the system. Thus, the direction of objects and targets detected by this system was being observed with an increase of 107 degrees by the operator.
At 06:13:56, the air defense unit operator detected a target at his 250-degree azimuth, flying on a 52-degree course. At the same time, PS752 had been flying towards the defense system from a 143-degree azimuth. The aircraft was flying a 309-degree course.

At 06:14:21, the operator notified the specifications of the detected target to the Coordination Center over the communication network. The notification was not communicated successfully.

Meanwhile the system operator began analyzing the observable information and categorized the detected target as a threat. At 06:14:41, without receiving any response from the Coordination Center, the air defense unit operator fired a missile at the threatening target he had detected.

Under the applicable procedures, if the defense system operator cannot establish communication with the Coordination Center and does not receive the fire command, they are not authorized to fire.

The missile radio fuse was activated at 06:14:59. At that point flight PS752 was at 8100 feet at a position about 20 km west-northwest of the airport.

After the first missile radio fuse was activated, the air defense unit radar still locked on the target, and the defense system kept detecting and tracking it. By observing the continuity of trajectory of detected target, the second missile was fired at the aircraft by the operator of defense system at 06:15:11.

At 06:45:24, the last communication between the missile and the defense system was recorded in a place close to the aircraft route. After that, the defense system showed a message indicating the strike had failed, with the aircraft clearing from the radar lock-on after some time.

The aircraft turned to the right and about 06:16:11, a fire broke out on the aircraft, which was intensifying. Altitude was lost and at 06:18:23, the aircraft crashed into a playground in Khalajabad near Shahedshahr area, 15 km north of the airport. It disintegrated completely and wreckage was strewn along a 300 m long path.

Air India flight was at full speed while landing at Calicut Airport: DGCA

An Air India Express flight with over 190 passengers and crew members onboard skidded off the runway at the Kozhikode International airport in Kerala on Friday evening. DGCA officials told news agency ANI that the Dubai-Kozhikode aircraft was at “full speed” while landing at the Karipur Airport and overshot the runway.

At least 19 were killed after an Air India Express flight with over 190 passengers and crew members onboard skidded off the tabletop runway at the Kozhikode International airport in Kerala, also known as the Karipur Airport, on Friday evening.

The Air India Express flight skidded off the tabletop runway and fell into a 35-ft-deep valley breaking up into two parts on Friday evening, police sources said.

Both pilot and the co-pilot are among the 19 killed in the flight mishap.

The flight was coming from Dubai and was part of India’s Vande Bharat mission, an initiative to bring back stranded Indians from foreign countries.

The fuselage broke into two after the aircraft overshot the runway at Kalipur airport. The aircraft has been identified as IX 344.

Civil Aviation Minister Hardeep Singh Puri said that the flight, on its way from Dubai to Kozhikode, “overshot the runway in rainy conditions and went down 35 ft into a slope before breaking up into two pieces”.https://platform.twitter.com/embed/index.html?creatorScreenName=indiatoday&dnt=false&embedId=twitter-widget-0&frame=false&hideCard=false&hideThread=false&id=1291784427811401728&lang=en&origin=https%3A%2F%2Fwww.indiatoday.in%2Findia%2Fstory%2Fair-india-flight-was-at-full-speed-while-landing-at-calicut-airport-1708996-2020-08-07&siteScreenName=indiatoday&theme=light&widgetsVersion=223fc1c4%3A1596143124634&width=550px

“Weather conditions being what they are, I’m told aircraft couldn’t be brought to a halt. As a tabletop airport, it imposes a challenge. There was a 30-feet drop to the ground below. Fortunately, the plane that broke into two from fuselage didn’t catch fire,” Hardeep Singh Puri told India Today TV.ADVERTISEMENT

Inputs suggest that a missed approach was carried out first followed by a second attempt to land the aircraft when it overshot the runway.

The Kozhikode is a tabletop airport with deep gorges at both ends of the runway. The tabletop runway of the Kozhikode airport is said to be one of the riskiest runways for landings in India.

Pilot decision-making in poor weather contributed to fatal CFIT accident in Canada

TSB Canada found that pilot decision-making was a factor in a fatal controlled flight into terrain accident involving a Cessna 208B in 2019 near Mayo, Yukon.
On 6 August 2019, a Cessna 208B Supervan 900 operated by Alkan Air was on a visual flight rules (VFR) flight from Rau Airstrip to Mayo Airport, Canada, with one pilot and one passenger on board. While enroute, the aircraft entered an area of low visibility and low cloud ceilings. The aircraft departed from the intended route, turned into a box canyon and struck rising terrain, fatally injuring the pilot and passenger. The aircraft was destroyed and there was a brief post-impact fire.
The investigation found that the pilot’s decision to continue a low altitude flight into poor weather conditions in mountainous terrain was influenced by several factors. The pilot had recently completed a flight along the same route, in similar weather conditions. The pilot’s decision-making would have been affected by his familiarity with the route and, consequently, he likely did not consider an alternate route to avoid the poor weather conditions.
The high speed at low altitude and low visibility reduced the opportunities for the pilot to take alternative action to avoid terrain. Within the box canyon, the canyon floor elevation increased abruptly within less than one nautical mile and the low visibility prevented the pilot from detecting this and taking sufficient actions to prevent a collision. Additionally, the aircraft’s terrain awareness and warning system aural alerts were ineffective in warning the pilot of the rising terrain because he had already heard multiple similar alerts in the preceding minutes of flight, or had silenced these alerts.Following the occurrence, Alkan Air made changes to its Caravan operations, including requiring a second flight crew member for Cessna 208B Grand Caravan captains with less than 2000 hours. Before becoming a captain on the Caravan, candidates must perform as a second crew member on the Caravan for 1 season. The company has also made modifications to its emergency response plan.
