Over 30 years ago, one of the most infamous plane crashes ever took place - And it was likely caused by a small decision from the pilot to let his children into the cockpit.
Although it used to be common for children on long flights to be able to view the cockpit, it was rarely ever extended to them being able to sit in the pilots seat and touch any controls.
But, that wasn't the case in 1994 for Aeroflot Flight 593.

Flying from Sheremetyevo International Airport in Moscow, Russia to Kai Tak Airport in Hong Kong, relief captain Yaroslav Vladimirovich Kudrinsky was accompanied by his own children on board.
There were 75 people aboard the Aeroflot plane including his 13-year-old daughter and a 15-year-old son.
Once the plane had taken off, Kudrinsky took them up into the cockpit and put into autopilot mode.
And this is where things take a tragic turn.
So that she could feel as though she were flying the plane, he let his daughter sit in a piloting seat.

Next, his son got to do the same, but as the black box flight recorder later revealed, something clearly went wrong.
His son somehow accidentally turned on manual control of the plane, meaning that his playing with the flight controls was having real effects on the flying of the plane.
As he wrestled with the flight controls, autopilot was first turned off and then actually physically disengaged since he was making moves that it wasn't designed to accommodate.
As this was ongoing, distressing audio of the pilot's cabin that was recovered, reveals that the plane entered a steep banking turn that alerted the piloting crew to the problem.

After realising the crisis, the crew scrambled to fix the issue and attempted to stop the plane from spinning out of control.
The flight recorder shows that the plane began banking steeply, seeming to nearly get under control but then entering a near-vertical climb that caused it to stall and eventually spin down through the air.
The pilots were tragically unable to get the plane back on the ascent, and it eventually crashed into a mountainside below its flight plan.
As they scrambled to rectify the situation, the pilots' chilling final words were reported by the Cockpit Voice Recorder Database.

Kudrinsky is heard sobbing, saying: "Full power," while his co-pilot, Igor Vasilyevich Piskaryov, replies: "Speed is very high."
Piskaryov later says: "We're coming out, coming out!", Kudrinsky replies: "Done," and then Piskaryov adds with panic: "Gently! ... Sh*t, not again."
The last few words are pretty hard to make out, with Kudrinsky reportedly heard saying before impact: "We'll get out of this. Everything's fine... Gently [unintelligible], gently... Pull up gently!"
Just minutes from the moment Kudrinsky's son accidentally disengaged the autopilot, the plane was completely destroyed and all 75 people aboard tragically lost their lives.
