If the information I obtained is correct, inflatable airlocks are sealed by the air pressure and cannot be unlocked unless the pressure is lowered(correct me if I'm wrong).
Additionally, airlocks usually open "inwards". To be able to override this, they should open outwards, however, this will lessen its sealing ability.
Some inflatable airlocks are the MASH, AIA and LEIA. Also, I found a video on YouTube on operating the MASH. My apologies, I can't seem to find the link on where I read about the seals opening inwards.
Do inflatable airlocks that can be opened without lowering the pressure exist?
If not, is there any possible way to create this?
