Vortex encounters are not unusual. The effect can be turbulence and a sudden rolling motion. Maybe could have been descending and hit very different winds. These things are happening all the time. Because something you may consider 'unusual' appears to happen to your flight, it does not automatically mean you have diced with death, or the pilots are trying to kill you. People look out at other aeroplanes in the holding pattern and leap to a conclusion they have just avoided death by collision, or because they've gone around the pilots were trying to 'do them in', or they've landed and braked heavily 'the pilots must have landed deep- they must be sacked!'. Every flight is different, most have something 'unusual' or different happen. Sometimes aeroplanes rock roughly, or use speedbrakes a lot, or go around from approaches because the one in front is slow getting out of the way. But far too many people come on here wanting to find out if they have had a close experience of meeting their maker!
It gets very tedious for professional pilots, and whilst this is an aviation forum, it is still basically a 'Professional Pilots Forum' (that's what it still calls itself!), and it does seem in very bad taste if people still pop up trying to assemble evidence that they have been 'mishandled' or had a wrong done unto them! The extremely safe flying statistics say that if they have been mishandled to the extent they seem to believe, Europe would be littered with bodies and smoking wreckage! You drive your car, sometimes your gear changes are not the best. Sometimes somebody steps out into the road and you have to brake sharply. Traffic lights change and hold you slow up after sharp braking. At no stage have you 'nearly crashed'. Why do people think the slightest thing out of the 'ordinary' on a flight needs open examination afterwards?
If you are nervous, accept you are so. get through it and don't try and find out what every lurch and bump is afterwards. Some landings are heavy. It doesn't matter. If the aeroplane can still fly, it's fine. Flight recorders are watching everything anyway- anything out of order will be drawn to attention. So sit back, relax and enjoy the flight, because there's nothing you can do anyway, and if you are still alive afterwards, nothing really went wrong, did it?
