Grumman XTSF Hi Bushranger I ve suggested an alt for this articles DYK just so you know With regards to the B class assessment you ve requested the only thing I think I d like to see is a clearer ref for the last sentence of the lead I m guessing its already covered in the last few refs but if it could be a tiny bit clearer that would be better The lead is a bit short although I appreciate its a short article but if you could extend it by a sentence or two that would be excellent Cheers
