Not having the sheet on me the question is something like "what does the TS originally stand for in the british aircraft TSR-II, the R is Reconnaissance. There's also a bit about how it was privately made and so originially had the code of PV"
I too found 3 answers for this, 1 related to the TSR-1 and what the TS stood for in that (so covered the original bit), one was for the TSR-2 (and mentioned the PV bit) and one said that the plane was a 3-seater ans so that was what the TS stood for.
It took me a while to pick a winner too!
