When approaching the speed of sound the
- pressure above the wing exceeds the pressure below the wing in places
- pressure above the wing equals the pressure below the wing
- pressure above the wing can never exceed the pressure below the wing
Explanation from PART66Online
Near the speed of sound, the flow accelerates strongly over the upper surface and a shock can form, with localised separation. Behind such a region the upper-surface static pressure can locally rise above the lower-surface pressure in places, disturbing the normal lift distribution that exists at lower speeds.

Can somebody place full question and answer? Should it be "speed of sound"?

yeah it should;ve been speed of sound but for some reason the moderators dont fix the questions .
