Oh! Fantastic - if only I'd known! Love a bit of Russian
Thanks guys. It was quite low and yes, not unpleasant at all, just a peculiar sound compared to the usual Easyjet and Ryanair we get here.
We're by the coast near Whitstable and get a clear view out the back probably as far as London/Oxford on a clear day...quite wonderful, sunsets lighting the planes up pink at times.
Moved here recently from a lower floor flat so it's a revelation.
