Re Smirnoff…I think it was him that upset the British authorities by radioing the weather details back to Amsterdam on a KLM service to Shoreham in the ‘phoney war’ period.
The 1941 Lufthansa timetable is interesting….possibly somewhat affected by the invasion of the USSR. I can’t see any frequency or days of the week info for the route to Lissabon (Lisbon)

The Jenny Gradidge Air Britain DC-3 book has C-47 19393 42-100930, interned Portugal 16July 1944, to Tranportes Aereos Militares as D-2/ CS-EDB, then 28 May 1945 to T.A.P as CS-TDA…derelict Mozambique 2003. So it’s a reasonable assumption that it’s the unmarked C-47 in the Portela photo post #205 giving that a ‘not before’date of 16 July 1944

The Aero Portuguesa Lodestar is CS-ADD. the Spanish Douglas is a DC-2. I think the unmarked C-47 was the first impounded by the Portuguese. The photo came from the air museum at Alverca about 10 years ago, though it had been published before and was on Key in 2011 http://forum.keypublishing.com/showthread.php?111975-Wartime-landings-in-Portugal which has a link to a blog about forced landings in Portugal http://landinportugal.blogspot.co.uk/

This view fromthe Portela tower around early 1944 does seem to show two intersecting runways but I’ve never seen a plan of the airfield layout[ATTACH=CONFIG]254140[/ATTACH]

Re post#193 , the DH Albatross was incapable of linking the UK with Lisbon after the Bordeaux refuelling stop was lost with the fall of France. I think one was stranded at Lisbon and had to have fuel added in flight from drums by lifting the floorboards above the fuel tanks to get back to the UK. Re post #195 possibly Sabena’s neutrality markings were applied to the pre-war white? paint job of the Savoias and the bare metal of their DC-3s then orange paint applied later as with KLMs fleet…maybe they didn’t all get the orange paint?

Probably British Airways Ju52
