Thank you.
Your concrete battleship clue narrowed the search area considerably, and provided a fascinating piece of history as a diversion.
It wasn't too hard to then find an ASW base nearby.
Nothing handy at the moment so Open House

French P4BYPrivateer ,possibly in `Indochine`...
Got to clamber over/in one of the firefighters in Boise ,ID,2-crew,full of GPS and auto `drop`gear...

I'm just over 70 and due to the fact that the TV companies seem to transmit the best programmes between midnight and about 4 am I hardly ever get to bed.
Photo taken at Blackbushe?

Do you not have Catchup or digital recording kit ?

We watch late-night stuff the following day when there's a lot of rubbish on TV.

We are not at Blackbushe or in Indochina.

If not Indochina/Tan Son Nhut then it must be Tunisia - La Karouba Air Base.

Sorry - not Tunisia.

Leave Africa.

I suggested above to leave Africa.

I had to look that up.

Are we still in the Pacific...?

No. We're in the Arabian Sea.

As a rather long shot, what about Socotra to the East of Yemen, possibly on the edges of the Arabian Sea, but still French as I understand. Not that much if any history of the airfield, seems to be available either.

It's not there either but so far you are closest.

I think most of you are being seduced by a French aeroplane.

This was once an RAF airfield.

May we stick to finding the challenge please instead of making inflammatory comments.

PM shortly for SLB.
