The Lockheed SR-71 "Blackbird" was an American strategic reconnaissance aircraft that traveled at over mach 3, or 3 times the speed of sound. The Concorde was a French passenger jet with a top speed of just over mach 2. The Bell X-1 was the first supersonic test plane and had to be dropped from a larger plane to reach altitude.
For a person with blood type A- (A negative), they can be transfused with either blood type A negative , or blood type O negative.
This is because any other blood type will immediately be rejected by their body.
A person with blood type A negative has got antibodies against any other blood type which has a rhesus positive factor as well as antibodies against any other blood type of a different group such as B and AB, even if they are rhesus negative.
Therefore because of the rhesus negative factor, a person with blood type A negative can only be transfused with rhesus negative .
