The Aircraft mission was Calibration flight. The flight was planned for departure from Mehrabad airport, Tehran to Kish Island airport. Eight persons were onboard of the aircraft (3 Pilots, 4 Ground technicians, a Security guard member). The flight was under operation of Iran Aseman Airline with valid Air Operation Certificate (AOC No; FS-102). The aircraft has taken off from RWY 29L from THR airport at 15:03 Local time and reached to cruise level FL270.The aircraft has landed on RWY 09 L Kish island airports at 16:44 local time. Four ground technicians have got off from the aircraft and refueling was done. At time 17:44 LMT , the aircraft has taken off RWY 27R and requested to join Right downwind up to 1000 ft. and 8 miles from the airport. After successful performing 7 complete flight (approach & climbing) for Navigation – Aids inspection purposes; at the 8th cycle, just at turning to the final stage of approach before runway threshold the aircraft crashed into the sea and was destroyed at time 18:45 local time. All four occupants were killed.

For unknown reasons, the aircraft landed hard at Kish Island Airport and was considered as damaged beyond repair. All 158 occupants escaped uninjured.

Flight IR451 arrived at Bandar Abbas (BND) from Tehran (THR) at 08:40. The Airbus A300 was to continue to Dubai (DXB) as flight IR655. Prior to departure the crew received an enroute clearance to Dubai via the flight planned route A59 and A59W at FL140. The flight took off from runway 21 at 10:17 hours and climbed straight ahead. Two minutes later, the crew reported leaving 3500 feet for FL140 on Airway A59, estimating MOBET at 06:53 UTC (10:23 Iran time). At 10:24:00 the aircraft passed MOBET out of FL120. At 10:24:43 two Airbus was hit by surface-to-air missiles. The tail and one wing broke off as a result of the explosions. Control was lost and the aircraft crashed into the sea. The missiles were fired by the US Navy cruiser USS Vincennes. It was operating in the area together with the frigates USS Elmer Montgomery and USS John H. Sides. They were to protect other ships in the area. At about the time the Airbus took off, the radar aboard the USS Vincennes picked up a brief IFF mode 2 response, which led to the mistaken identification of the Airbus as a hostile F-14 aircraft. The USS Vincennes issued 7 challenges on the Military Air Distress (MAD) frequency 243 MHz, addressed to 'Iranian aircraft', 'Iranian fighter' or 'Iranian F-14'. These messages were followed by three challenges on the IAD (International Air Defence) radio frequency. Due to increasing tension in the area - on May 17, 1987 an Iraqi Mirage had attacked USS Stark - all aircraft in the area had to monitor 121.5 Mhz: the International Air Defence - IAD radio frequency. There was no response. Meanwhile radar operators were monitoring the Aegis screens. They reported that the incoming plane was descending with an increasing speed. In fact, the Airbus was climbing. Considering itself and USS Montgomery under aggression, USS Vincennes took the ultimate decision to launch missiles against the perceived hostile target at 10:24:22.
It remains uncertain whether the IR655 flight crew (only able to monitor the IAD, not the MAD frequencies) would have been able to rapidly identify their flight as the subject of the challenges made by the USS Vincennes.

On final approach to Bandar Abbas Airport, the airplane was too low for undetermined reason when it struck the ground and came to rest in flames few dozen yards short of runway. Eleven passengers were killed while 17 other occupants were evacuated. The aircraft was destroyed.

The Wellington flew over the ship christened 'SS Afghanistan' anchored off the island of Abu Musa to drop a message on board. Unfortunately in doing so, the pilot misjudged his height and struck the top of one of the ship's masts, carrying it away, and damaging the tail and rudder of his aircraft. After jettisoning its petrol, the plane made a belly landing on the island. The crew were uninjured and were taken to Sharjah the same days by launch. The airplane was later declared as written off.

For unknown reasons, the aircraft departed Bandar Lengeh Airport with delay. Thus, the crew started the approach to Jask Airport by night and limited visibility. On short final, the aircraft was too low and impacted the ground short of runway threshold. Upon impact, the the fuel tank ruptured and the aircraft caught fire before coming to rest, bursting into flames. Two passengers were rescued while three other occupants were killed.
