Don't do it!
I was on a CityFlyer out of LGW a couple of years back. AFAIR it was an ATR or some such godforsaken noise machine. Anyway, I'm seated in row 1 right up by the bulkhead where the noise resonated beautifully. I'm not talking mild droning, but full on pain between the eyes. Head felt like it was falling off when we arrived in LUX.
So my hints for a peaceful prop filght? Don't. Dr if you must, take ear plugs!
