both ctors in the subclasses Pilot and BlimpPilot set the Person's member variable m_Name
Pilot(std::string &name) : Person(name) {m_Name = name;}
BlimpPilot(std::string &name) : Pilot(name) {m_Name = name;}
this is not needed and already done by the Person ctor :
Person(std::string name)
{
m_Name = name;
}
thus, to avoid unneeded (and error prone) work , the ctors should be
Person(std::string name){m_Name = name;} // does the affectation of m_Name
Pilot(std::string &name) : Person(name) {} // calls 'Person' ctor
BlimpPilot(std::string &name) : Pilot(name) {} // calls Pilot' ctor
