"POD" concept for manned orbital insertion

This is a concept to "rethink" how we get astronauts into orbit. Instead of constructing a vehicle and making it an environmental envelope for the astronauts, we make individual environmental "PODS" for each astronaut and create a lifting system to deliver the "PODS" to an orbital ship or the space station. It is far easier to create a hardened egg-like environment (as opposed to a ship) which meets vehicle lifting capabilities. This concept has greater viable surviveability in case of catastrophic failure than what we have now.
