An airliner has layers upon layers of safety redundancies.
There are multiple flight computers. Practically every essential sensor has copies. Oxygen generation, ram air turbine, life jackets, inflated boats. Onboard radar. TCAS. The airplane itself glides. Then there are thousands of procedural rules and regulations for safe operation.
A system like starship that relies on precise active propulsion has no such room for error.
You've clearly padded your list to look more negative because your last sentence only applies to the glide part... Starship obviously has the same redundant flight computers and sensors and radar and TCAS and will have thousands of procedures for safe operation.
I was responding to the parent, explaining the layers of safety in an airliner.
And you missed the point. The airplanes wings give it a passive way to glide down. Parachutes also give a passive way for a capsule to fly down. Starship has no such system, either the propulsion works or the rocket just falls out of the sky. There are thousands and thousands of different ways that the propulsion can get screwed up.
Launch vehicles with capsules have redundant escape systems. If the vehicle during ascent is malfunctioning the crew can escape and safely land. In starship the crew will just blow up and die.
Starship is NOT man rated so let’s see what SpaceX comes up with. But one cannot ignore the glaring issues with the design.
