Gosfield and Wattisham are 292 ft AMSL but neither fit the picture.

Actually Jenkins, it is Williamtown. Williamstown is a suburb of Melbourne. Confusing, I know...

I will confirm that winner.

Many thanks...

I'll do my best to respond promptly to any queries and suggestions...

Sutton Bridge, Lincolnshire? An addition of thanks to Dora-9 for nudge on Melbourne. Fine city, oldest school chum there, in Malvern having left Malvern UK in 1967.

Maybe Oirland.

Yep, I'll take a stab at that. Poolbeg chimneys from Dublin Airport (remote corner of)

The only problem is that I can't find an airstrip/field around there except Baldonnell and it isn't that.

Auxtank,

Viewed from Dublin airport the two chimneys are almost in line.

Indeed. Hummm...

Not the Emerald Isle, I'm afraid, though another place nearby regularly hosts visitors from there, nor Lincolnshire, on which I might comment further later on.

I was thinking racehorses.

Now I'm wondering how visitors can be mineral.

Strictly speaking, my dictionary confirms that I'm using the word outside its usual meaning, but only as others here do, especially the unlicensed.

As in fizzy drinks ?

This challenge has taken a decidedly surreal angle.

TheiC - are we in England?
