If you think Matthew 24:29-30 was fulfilled in 70AD I would like to hear why you believe so
[Mat 24:29-30 KJV] 29 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken: 30 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
I would argue what was fulfilled in 70 AD was fulfillment of the warning God gave regarding the physical/material/natural sons of Abraham, called the nation of Israel. The physical destruction of Jerusalem and the Old Temple in 70 AD made a total and complete end of the Old Covenantal sacrificial system, because Christ has ushered in a New Covenant through His crucifixion and resurrection which began a new sacrificial system through His blood.
The New Covenant has no part in the Old Covenantal way through being cleansed outwardly by the blood of sacrificial animals and offerings. These all show the physical/material way of Old where the Jews were commanded to keep the whole law of God if they desired to be saved. The New Covenant, through the sinless life, death and resurrection of Christ came with Christ, when He introduced to man the way we might be, not only outwardly cleansed, but inwardly cleansed.
The New Covenant didn't come to the earth when Jerusalem and the Temple were utterly destroyed. It came with Christ when He came to earth a man, lived a sinless life, gave His blood to atone for sin, and resurrect from the dead to destroy the bondage of death that Satan was able to hold unsaved people in. While here Christ shows us the Kingdom of God had come by the miracles He performed, especially casting out devils/demons. This also demonstrates the Kingdom of God in heaven is spiritual and can only be known and entered through His Spirit in us.
The new way Christ came with that man might be eternally saved is by knowing and entering the Kingdom of God in heaven through His Spirit in us. Christ says we must be born again.
Though some of what Christ spoke on the Mount of Olives was to be physically fulfilled as history shows us. The majority of the words Christ spoke cannot fit into the physical/material destruction of 70 AD. We don't force the prophetic word Christ spoke into the far distant future, or end of this age only, but understanding the words Christ spoke to His disciples then would witness/suffer the things spoken along with new disciples that would come through their faithfulness as long as the gospel of the Kingdom of God is proclaimed unto all the nations of the earth.
Knowing that Christ ushered in the Kingdom of God from heaven cannot be physically seen by the world. and the only way to both know and enter the Kingdom of God is we must be born again. Christ tells us this is because the Kingdom of God is within you. Knowing this we should also realize the things Christ warns His disciples should come, though there will be much physical suffering and death through that which was coming, it can only be rightly understood through spiritual, not material/physical fulfillment as a spiritual battle between good and evil is waged.
The New Covenant through Christ is not physical and does not make sense when we try to force fulfillment for the prophecy unto physical/material/natural children of Abraham. The Kingdom of God that Christ came to earth with is a spiritual Kingdom and the prophecy only makes sense when we separate the wrath of God that came upon a physical people who were called to be the Kingdom of God on earth in 70 AD, from the warnings of all that would come to the spiritual people of Abraham from the beginning of proclaiming the gospel of the Kingdom of God unto all the earth until the Kingdom of God in heaven is complete.
