A bubble canopy is a canopy made without bracing, which attempts to provide 360° vision to the pilot. Bubble canopy designs vary. Some, like on later versions of the F4U Corsair, are built into the upper rear fuselage, while others, like the canopy of the P-51D Mustang and most modern fighter aircraft, are built flush with the fuselage, providing unobstructed rear visibility.
