Used to fly a lot in Russia and FSU, so many tragi-funny memories:

Steps wheeled away from aircraft while would-be passengers are still standing on them...

One lucky passenger hoisting self from ramp
through door after steps were removed ....

Standing for 4 hours on one internal flight .....

Turkeys pecking through box under seat in front ...
