Gemini didn’t have an airlock. Apollo didn’t have an airlock. Just means those inside the capsule have to suit up.
The danger is if the hatch doesn’t seal again you are now trapped in your suits without cabin pressure. Airlocks have a valid purpose. The Dragon is the safest orbital vehicle humans have ever designed period full stop. If they cannot seal the hatch Dragon can do a deorbit burn and come directly in a ballistic entry it’s PICA heat shield can take that it’s 8+ Gs but the spacecraft is rated for it. While NASA won’t allow it the onbroad Super Drago engines have the delta V for a ground landing anywhere anytime land or sea it was originally designed to land well on land under power of its engines not parachutes. NASA being risk adverse said no way but the fuel ,thrust and capabilities are still there. I would go up in Dragon without hesitation and comeback on land under power not parachutes...engines burn or your dead. I would trust the best aeronautical engineers in the world. They have proven record of excellence.
