That article makes out as if transmission blocking leads to a safety problem if a transmission gets lost. It doesn't. What that article misses is that aviation radio communications require readback and verification of the readback, in safety critical instructions such as "cleared for take-off". Not just for radio transmission blocking reasons, but also to detect mistakes in mishearing instructions.

https://en.wikipedia.org/wiki/Tenerife_airport_disaster#Comm... tells a more accurate story: the root cause was that the captain assumed they were cleared for take-off without actually hearing their own callsign and the word "cleared".

Since then, the word "take-off" is avoided in any other type of communication (eg. you might hear "report ready for departure" but never "report ready for take-off"), and every pilot knows never to assume that a clearance has been given unless they hear those exact words together with their callsign.
