Right after take-off (which means an airplane already exceeded V1) it is recommended that an airplane keeps climbing even when emergency occurs. Beside worries of crashing into houses and buildings by flying low altitude, why should an airplane not stop climbing up? Why should it climb up and then, lowers to some altitude and then land?

In the days of my youth I in was in the air cadets and we used to fly in Chipmunk training airplanes. I remember being told you should never attempt to turn shortly after takeoff because you weren't at full speed and turning risks stalling the inside wingtip. If you do that the result is a spin and probably a crash.
The rules were that if a problem arose immediately after takeoff you landed in a straight line and hoped the runway was long enough. At higher altitude you attempted to reach cruising speed then you turned. I asked the instructor what happened in between, and he told me that if he survived I'd be in trouble :-).

A quick Google found this article (amongst many others). Look for section "Cross-Control Stalls". It basically agrees with what I've posted above though I've made it sound a bit too simple.
