Airline pilots have to follow laws that mandate rest periods. On very long flights it is normal to have extra crew. This extra crew will alternate throughout the flight in order to have a rested pilot in command at all times. Some airplanes have bunks for the resting crew.

No time at all
If you are talking about the Concord, then I believe it is because the "nose" was so long that the pilots had a hard time seeing the runway. So they made it pivot, so the pilots could see.
yes you can, you have to be flexable and "long"
In 2014 in America (latest statistics available), there were a total of 593,499 pilots certified by the FAA. In 2008 in America (for comparison with Canada), there were a total of 613,746 pilots certified by the FAA. In 2008 in Canada, (last statistics available), there were a total of 64,932 pilots certified by Transport Canada. In both countries, very roughly 0.2% of the population are pilots. That's very roughly 1 in 500 civilians. Military pilots are not included. In 2010 in the UK, there were 21,063 civil aircraft registered, and about 28,000 Private Pilots, and 10,000 certified glider pilots.
basically flights under 3 hours basically flights under 3 hours basically flights under 3 hours
If birds are going to fly for long periods of time to distant locations during migration, then they will burn a lot of energy.
pretty long
It should be roughly 7 hours non-stop. However, such flights are rare and flights with layovers can be at least 10 hours long.
I don't know the rules but on recent 14 hour Air Canada flights from Toronto to Beijing and Shanghai to Toronto there were 4 very mature pilots.....one with 4 stripes and 3 with 3 stripes. I was told by the flight attendant that there was a captain, co-pilot, relief pilot and 2nd officer.
it depends where you live
