IIRC, at that time there was no standard unambiguous way to communicate standard procedures and misunderstandings were often (albeit not fatal). It was after that crash when FAA introduced very strict rules on air traffic communication (e.g. the word "clearance" can only be said by the air traffic controller if the clearance is actually granted). Talk about rules written in blood.

"Clearance" is used in many ways to indicate that a clearance has not been granted yet (or has been revoked). From the ATC Job Order manual [0], examples include: “continue, expect landing clearance two mile final” and "CANCEL TAKEOFF CLEARANCE (reason)" What you might be thinking of is the guidance against using "takeoff", which is "Avoid using the term “takeoff” except to actually clear an aircraft for takeoff or to cancel a takeoff clearance. Use such terms as “depart,” “departure,” or “fly” in clearances when necessary" [0] - https://www.faa.gov/documentLibrary/media/Order/7110.65X_w_CHG1_CHG2_and_CHG_3.pdf https://www.faa.gov/documentLibrary/media/Order/7110.65X_w_C...
