I was a passenger on this plane. The pilots skill actually saved us from being incinerated in a fireball. Even though it was their mistake by inputting the wrong weight, they were also using reduced thrust as it is Emirates policy to save money. The practice of using reduced thrust when taking off should be outlawed. This incident has cost Emirates far more than the cost of the fuel they saved.
Also flames flared from an engine on the right wing while taxiing before the tailstrike occurred. Was this a factor in the tailstrike? No-one has mentioned this.
The most dangerous aspects of any flight are taking off and landing, maybe Emirates and the other airline companies should reconsider the dubious practice of using reduced thrust when taking off.
