Don’t try your luck on Russian airlines. Back in the day, little 80 year old grandma’s would drive the fuel truck out to your plane and climb on the wing with the hose. No gauges so they’d have to peek in the hole to see if they needed pump more. Peek - pump more - peek - pump more. I’m not joking. Every one I saw was ancient and could barely get around. Why didn’t they hire 20 somethings? Who knows, it was Russia.
Damned it ! Wonder what they do for A2A refueling ? Add Ductape to sunglasses and a couple of cotton balls in the ears ?
