Reflecting on NTSB issued preliminary report for its ongoing investigation of the Nov. 4 crash of a UPS

Because there were two Aft Lugs, the fatigue cracks were hidden from the outside. You wouldn't find them on a visual inspection unless you removed the spherical bearing. Look for the triangular shape on the Aft Lug fracture surface in the picture above. That's the fatigue crack. It grows until the rest of the area can't handle the load and then fails in tensile overload. Then the Forward Lug, holding all the load, fails in pure tensile overload. Terrifying.

Newly released dash cam video of the plane right before it hit the ground shows the #1 engine totally gone in the UPS accident.

Aeroflot 593 crashed in 1994 when the pilot let his children control the aircraft. This is the crash animation and audio log.

Aeroflot Flight 593 was a regular passenger flight from Sheremetyevo International Airport, Moscow, to Kai Tak Airport in Hong Kong. On 23 March 1994, the aircraft operating the route, an Airbus A310-304 flown by Aeroflot – Russian International Airlines, crashed into a mountain range in Kemerovo Oblast, Russia, killing all 63 passengers and 12 crew members on board.
No evidence of a technical malfunction was found. Cockpit voice and flight data recorders revealed the presence of the relief pilot's 12-year-old daughter and 16-year-old son on the flight deck. While seated at the controls, the pilot's son had unknowingly disengaged the A310's autopilot control of the aircraft's ailerons. The autopilot then disengaged completely causing the aircraft to roll into a steep bank and a near-vertical dive. Despite managing to level the aircraft, the first officer over-corrected when pulling up, causing the plane to stall and enter into a spin; the pilots managed to level the aircraft off once more, but by then the plane had lost too much altitude to recover and crashed into the Kuznetsk Alatau mountain range.

Turbulence: Not as Scary as It Feels

For passengers & aviation professionals

🌀 What is turbulence?
Turbulence is irregular motion of air due to eddies and vertical air currents. It can shake the aircraft, but it doesn’t mean something is wrong—it’s a natural atmospheric phenomenon.

💡 Is it dangerous?
Not at all. Aircraft are designed and certified to handle even severe turbulence. Most injuries come from not wearing seatbelts. So, always stay buckled up—just like pilots do.

🌪️ Types of Turbulence (based on meteorology training):

1. Mechanical Turbulence

Occurs when air flows over rough terrain or man-made obstacles (like buildings or mountains). The disruption of smooth airflow causes eddies and bumps.
➡️ Common during take-off and landing near mountainous or urban areas.

2. Thermal Turbulence (Convective)

Caused by rising columns of warm air (thermals) during daytime heating.
➡️ Often felt during mid-day flights over land, especially in summer.

3. Frontal Turbulence

Occurs when a cold front pushes under a warm air mass, lifting it abruptly. The stronger the temperature contrast and wind shift, the bumpier the ride.
➡️ Can be found in frontal zones, especially with fast-moving cold fronts.

4. Clear Air Turbulence (CAT)

Found at high altitudes (typically above 20,000 ft) near jet streams, tropopause, or mountain waves. It happens without visible clouds, hence the name.
➡️ Can be sudden and severe, but aircraft structure is built for it.

🧠 For Pilots

Use preflight weather tools like SIGMETs, PIREPs, and upper-level charts to plan for likely turbulence. Knowing the cause (thermal, mechanical, etc.) helps in anticipating its strength and location.
Avoiding it when possible is always better than enduring it.

✅ Bottom line:

Turbulence is uncomfortable—but not unsafe. Stay buckled, stay informed, and trust your crew. The sky may shake, but the aircraft remains strong.

Flight 🛫 control surfaces
It is the rules of control and according to the components mentioned in the shape of the aircraft and these are for the basic surfaces of the aircraft and thus it is clear as follows
In aviation, flight control surfaces are essential for maneuvering and stability of an aircraft. There are six basic flight control surfaces:

1️⃣ AILERONS: Located on the rear edges of the wings, they control rolling by moving in opposite directions. When one of the winglets rises, the other falls, causing the plane to flip along with the low aileron.

2️⃣ SPOILERS: The spoilers are placed on the upper surface of the wings, reducing lift and increasing drag when deployed. They are used to aid in landing and to help slow down the aircraft when landing.

3️⃣ FLAPS: Located on the rear edge of the wings, the flaps extend downwards to increase lift and pull. This allows for a more controlled flight during take-off and landing.

4️⃣ SLAT: Located on the front edge of the wings, the slats extend forward to create additional lift at low speeds, improving aircraft performance during takeoff and landing.

5️⃣ RUDDER: It is placed on the vertical stabilizer at the tail of the aircraft, and the rudder controls the diffraction. It moves left or right to guide the nose of the aircraft in the opposite direction, aiding in directional control.

6️⃣ ELEVATOR: Connected to the horizontal stabilizer of the rear plane, it controls the degree of inclination of the elevators. By moving up or down, they cause the nose of the aircraft to rise or fall, making it easier to climb and descend.

These control surfaces work in unison to enable precise maneuverability and ensure safe and stable flight.

Jet Engine Cutaway – How It Works!
✈️🔥⚙️
This diagram on the engine shows the flow of air and power inside a high-bypass turbofan:
Compression Stages:
- Low, Intermediate, High Pressure Compressors – squeeze incoming air for combustion
- Each stage increases air pressure progressively
Combustion Chamber:
- Fuel is added and ignited, creating hot high-pressure gas
Turbine Stages:
- High, Intermediate, Low Pressure Turbines – extract energy from hot gases to power compressors and the fan
- The Low Pressure Turbine (6 stages) turns the big front fan
Bearings (Ball & Roller):
- Ensure smooth spinning of shafts inside the engine
