Thanks for that Airbedane - thought it might be the radiator, but was curious as the programme had it to display/dogfight with the SE5A/Brisfit & Triplane, but if I remember it correctly, after take off it only performed one flypast before landing agin. Still, as you say it was HOT! Glad to see it in the air one more time, sad that its flying days are nearly over.
