This mission is ridiculous, I have attempted it 7 times, even on casual. How htey expect you to fly that far with only you, no wingemn to defend you, 10+ aircraft on you, usingt he tailgunner which overheats constantly every 5 seconds so you cant fire while the enemy are shredding your plane to bits. Ive died 7 times with my plane going down.

Just cant complete this missions, its bit overboard.
This game started off fun with Casual mode (They say FUN) but later missions just got ridiculpous difficult on casual
