Pendaratan Tanpa Roda: Pakistan International Airlines Flight 300
Flying: What’s the strangest incident that’s happened on a commercial airline flight?
Obaidullah Khawaja
Obaidullah Khawaja, Founder and CEO at Sovoia
Here’s a good one thats popular with us Pakistanis in an ironic sort of way. In 1986 Pakistan International Airlines Flight 300 had a belly landing at Islamabad airport because the pilot forgot to lower the landing gear. That’s right, he simply forgot to lower the gear on a 747 jet. There were no injuries and the plane continued to fly for 19 more years after repairs
EDIT: So now I do know exactly how this happened thanks to a reliable source (name can’t be taken because he still flies planes)
There were 3 people in the cockpit that day, the pilot, co-pilot and I think what’s called the 1st officer. Normally there is an electronic safety system that alerts the guys in the cockpit about things such as the landing gear not being down.
This system is generally found to be irritating by pilots who can be quite dismissive and macho – trusting their own skills. In those days it apparently also made some errors in logic. And finally it goes “Warning! Warning!” in a loud shrill voice. So it was standard for PIA pilots at least to switch off the circuit breaker for this system and switch it back at 1000 ft
It was standard for the cockpit crew to switch back the warning system and for each of them to check that the landing gear is down as part of their landing checklist.
None of these things happened so the pilot basically landed the plane thinking that the landing gear was down. He only realised after hitting the ground that it wasn’t
The pilot called HQ right after getting off the plane and tendered his resignation. He never flew again.
The co-pilot Capt Ahsan Aftab Bilgrami flew again but unfortunately died when the plane he was flying crashed in the Himlayas near Gilgit
Boeing were ecstatic, apparently this is one scenario they had not stress-tested for
Here are some incredible pictures
EDIT: Since the above story has been so popular I thought I’d add another story from the 1970s which probably set the precedent for heroics by future generations of Pakistani pilots
According to http://www.historyofpia.com/acci…, the two pilots Salhejee and Mir had a misunderstanding about which one of them was flying the plane in the midst of a storm.
According to the site:
” The landing was going to be made by Capt. Mir. The weather was bad and Mir asked Salehjee to take over for the landing. Somehow, Salehjee didn’t hear the request, Mir thought that he had and so the approach was flown with nobody at the controls until impact! The pilots were unable to regain control of the aircraft and it veered off the runway. The Boeing 707’s main under carriage collapsed as it struck the runway very hard.
As seen in this photo, soon after aircraft’s crash landing PIA logo and titles were painted out from its tail and fuselage because Pakistan’s then Prime Minister Zulfiqar Ali Bhutto was due to arrive at the same airport on a VVIP PIA flight few days later. Later, this Boeing 707 was repaired and returned to active service with PIA”
Fly PIA – each plane has made history one way or the other

Benetech GM320 Infrared Thermometer Instruction Manual
A. Introduction
This infrared thermometer is used for measuring the temperature of the object’s surface, which is applicable for various hot, hazardous or hard-to-reach objects without contact safely and quickly.
This unit consist of Optics, Temperature Sensor Signal amplifier, Processing circuit and LCD Display. The Optics collected the infrared energy emitted by object ancj focus onto the Sensor. Then the sensor translates the energy into an electricity signal. This signal will be turned out to be digital shown on the LCD after the signal amplifier and processing circuit.
B. Warning & Cautions
1. Warning:
To avoid the potential situation may cause harm or damage to people, please pay attention to the following items:
- Before you use this unit, check on the plastic housing carefully. If there is aoy damage, do not use it.
- Do not point laser directly at eye or indirectly off reflective surfaces.
- Do not use this unit in the environment of explosive gas, steam or dusty.
2. Caution:
To avoid the damage of the unit or the target, please protect from the following situations:
- EMF (electro-magnetic fields) from arc welders, induction heaters.
- Thermal shock (caused by large or abrupt ambient temperature changes-allow 30 minutes for unit to stabilize before use.
- Do not leave the unit on or near objects of high temperature
C. Distance to Spot size
1. When take measurement, pay attention to the Distance to Spot Size. As the Distance (D) from the target surface increases, the spot size (S) of the area measured by the unit becomes larger.
The Distance to Spot size of the unit is 12:1
***This unit is equipped with a laser, which is used% for aiming.
2. Field of view:
Make sure the target is larger than the unit’s spot size. The smaller the target the closer measure distance. When accuracy is critical, make sure the target is at least twice as large as the spot size.
D. Emissivity
Most organic materials and painted or oxidized surfaces have an emissivity of 0.95 (pre-set in the unit). Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate, cover the target surface with masking tape or flat black paint. Measure the tape or painted surface when the tape or painted reach the same temperature as the material underneath.
E. Operation
1. Operating the unit:
- Open the battery door and insert 2*1.5V AAA batteries properly;
- Pull the trigger to turn on the unit;
- Aim at the target surface and pull the trigger, then temperature will be shown on the LCD. This unit is equipped with a laser, which is only used for aiming.
2. Locating a Hot Soot:
To find a hot spot, aim the thermometer outside of interest, then scan across with an up and down motion until you locate the hot spot. (Figure 3)
