Opinions please (impact Allied fighter bombers on D-day)

[indianer]

In one respect I would agree with Jukka about what would happen if aircraft stopped working on June 5 :
despite the huge air superiority of the allies, the germans inflicted heavy casualties and tactical defeats (Goodwood, to name one) and blunting of the offensive (Totalize) in Normandy. Air superiority was negated by german ground combat effectiveness and the vast inferiority of the Sherman vs the Panther (and the Tiger, tiny though its numbers were).

Anyway, on the subject of german armour in Normandy, frankly michael kenny (mkenny on this thread) is one of the experts (he is a regular contributor to feldgrau). Perhaps he can share more combat reports.
The chestnut about Typhoon rockets killing Wittman, by the way, has been well and truly buried by Brian Reid (in "No Holding Back"), a clear-eyed look at Totalize.
