"Do takeoff of" can be interpreted in various ways depending upon the context. However, antonyms for this phrase could include "make a landing," "cancel a flight," "remain grounded," "postpone departure," or "halt departure." These opposites describe actions that are contrary to the process of taking off, suggesting a lack of progress or delay. For instance, if a flight is canceled or delayed, it may not be able to take off as scheduled.
