All aircrafts are made in aerodynamic shapes so as to minimize drag. Space shuttles

too are similar to aircrafts. Yet the nose of all space shuttles are fat and blunt whereas

it is well known that a sharp narrow nose is highly aerodynamic and they are present in

all interceptor aircrafts and so on. Why this discrepancy?

Hi,

Many scientific ideas that are generally accepted by people today were formerly considered to be contrary to intuition and common sense.

Flat and blunt nose of aircrafts is one of them.

it was initially believed that highly streamlined shapes would be best for re-entering the earth's atmosphere.In fact, experiments proved that blunt-shaped re-entry bodies make the most efficient heat shields when returning to earth from space. So that is why Blunt-shaped re-entry vehicles have been used for all manned-spaceflights, including the Mercury, Gemini, Apollo and Space Shuttle missions
