Corpse in a plane doesn't change anything?

I know this was mid-eighties, when airports were Lax (no pun intended), but come on.

You have a DEAD BODY, a corpse in the plane, and this does NOT change the plane exiting procedure in ANY way. Police are not called, passengers not interviewed or detained, etc.

People exiting the plane don't even look shocked, horrified or even mildly worried.

How would you react if you suddenly had to walk past a dead body while exiting the plane? Would you think it's business as usual, a normal day, or would it be at least SLIGHTLY alarming to you? What would the flight attendands do, would there be announcements about it? Would people panic? Would people have questions? Why is none of this shown?

Also, how do the thugs know Matrix wasn't in the plane, in case the whole planeload of people might have been detained for questioning about a murder of someone? Do they have a list of passengers with photos to match so they can know exactly when the last passenger has exited the plane? What if Matrix was detained for a few minutes for one reason or another? How long would they wait? How do they know when THAT plane's last passenger has gone through, and what would they take as proof that Matrix ABSOLUTELY wasn't on the flight?

A body in a plane doesn't stink or smell at all, but it changes color and skin texture during those eleven (again this kind of number) hours? What?

How does the hat drop off the body at the exact moment of landing - with a perfect timing - , but not sooner? No turbulence or anything? What lucky flight..

Matrix just explodes buildings left and right, because he needs to have a 'hell break loose' - WITHOUT KNOWING which building his daughter is in!

Whaaattt???

This movie makes as much sense as a cockroach stuffing in a cheesecake. What the.. who greenlit this garbage?
