Are they all dead?
Dunno about all dead but assuming they would have been about 20 years old in 1940 they are not going to be very mobile now.
The BoB memorial flight used to have one of its aircraft painted in the colours of a 303 (Polish) Squadron.
Piss me off every year when everyone was marching through for remembrance day yet the commentators hardly mentioned the Polish pilots etc. When they do they mentioned them very briefly.
Worst still the Polish were not invited to victory march at the end of WWII because of their proximity with Russia in those days.
I would like them to be mentioned clearly or at least be invited to the march. Same for other commonwealth soldiers who I suspect not many are around anymore …
