Why the Skua had a flat-looking canopy

Why did the Blackburn Skua have such a flat-looking canopy?

Strengthened fuselage frames formed a crash pylon beneath the enclosure, so rollover protection and engine position shaped the cockpit profile.

Two specially strengthened fuselage frames supported the Skua's glazed enclosure and formed a crash pylon if the aircraft overturned on the ground. The pilot sat near the wing's leading edge with a broad view, while the engine position and protective structure constrained the canopy shape. The result was not the cleanest aerodynamic form. It gave a dive-bomber crew valuable rollover protection in a type exposed to hard landings and crashes.
