Thanks a lot for the report! Great to read over and get the feedback

Loads of aircraft!
That Sword Brethren formation is interesting and not something I would have thought of taking. Personally I tend to focus formations on either assault or shooting and would probably have gone for 2 Land Raider Crusaders with them instead, but it seems to work ok for you, only getting taken out right at the end after loads of fire pouring into it.
Did you find the Stormtalon's 15cm range attacks much of a disadvantage against the orks? The Fighta Bommers and Landa both have all round 15cm AA fire, so when attacking them you would have to come under fire from their defensive AA before being able to, potentially getting shot down before you attacked.
As you realised afterwards it's not possible to put Thunderhawk Transporters onto CAP as they're bombers. They can however come down and land on the ground to give all round 2 x 15cm AA5+ protection each to a particular area. The FW THT models are large models (measuring 9.5cm wide by 9.5cm long) and at being a WE formation they only need to be within 10cm of each other (coherency of 5cm x their DC), so 3 of them can give AA coverage to a fair size area.
