Jim and Ann live in Putney, south west London.
Living below the flight path of one of the world's busiest airports has its downsides — though very, very occasionally, when a stowaway falls from lowering landing-gear, it can be beneficial.
(Many years ago — back in the 1970s — I was a uniformed police officer at Putney, west London. I presume, due to security at far-flung airports being a lot less stringent back then, stowaways falling from the undercarriage of aircraft on final approach to Heathrow was pretty common. Often they travelled with all their worldly possessions — not all of it legal.)
