Me too... if you find it, let us know. Excellent film, remeber that shot of one backtracking after abandoning take off with the others still taking off...
Variation on the title might be "B-25 Mitchells do Fly IFR" of possibly even "Mitchells do Fly IFR". Can't quite remember, Shaggy's doesn't quite seem right.... I may well be wrong though (usually am!)
