Didn't they just kill about 30 thousand innocent women and children in Palestine exactly for this reason- because they happened to be near some bad guy (at least that is the excuse given)?

"Libyan Arab Airlines Flight 114 (LN 114) was a regularly scheduled civilian flight from Tripoli to Cairo, through Benghazi, that was shot down in 1973 by Israeli fighter jets after it entered by mistake, due to a system malfunction, the airspace of Egypt's Sinai Peninsula – then under Israeli occupation – resulting in the death of 108 civilians"
"The Israeli Cabinet discussed the incident three times in secret meetings. The minutes, declassified in 2023, show that the main decisions were to deny all responsibility and to refuse to hold an official inquiry"
But then, I think the only real difference between a civilian flight and a residential building is that in the first one there's people of many nationalities, while the bodies buried under the collapsed ruins of the building are all Palestinians, so we don't care much about them.
> one there's people of many nationalities
Yes, obviously PR and how the world will react is a big part of decision making.
Also, it's not the IAF pilots "didn't receive a response" to their signals. One of their pilots signaled twice (first with hand gestures, then again by dipping the wings of one of the jets). They did receive a response to first signal at least, but may have been confused by it, or have interpreted as an attempt to flee. It's also entirely possible the pilot of LN 114 was understandably confused and in a very tense mindstate and wasn't sure how to respond.
From WP:
It continued flying eastwards into the Sinai at a speed of 325 miles per hour (282 kn; 523 km/h), until the crew realised they had had problems with their instruments and were off their path; at this moment, the French pilot performed a U-turn, in order to leave the Sinai and go back towards Cairo.[6] The Israeli pilots interpreted it as an attempt to flee and, according to them, then tried to make visual contact with the airliner's crew and to communicate with them by signaling with their hands. Still according to the Israelis, the 727's French pilot responded with a hand gesture indicating refusal, signaling his intention to continue back on his way out of Sinai. The fighters claim to have replied by dipping their wings, what was once again ignored by the civilian airliner crew. Then, the Israeli fighters attacked the civilian plane.
