Have a good trip Andy. BTW, a quick way to cover the 'dish' in the seat, and also cover most of the seat, is to install the 'seat-type' parachute. Made from 'Milliput' and foil, it'll cover a multltude of sins !!
And of course, unless the aircraft was 'stood down', the parachute was more often than not in the seat - saved having to struggle to get the bl**dy thing on in a hurry!
