sustainable flight tech could be added

Theres research that can reduce warming effect of flying dramatically making it much closer to other long distance travel like driving

Using data from Japan’s airspace, they found that just two per cent of flights were responsible for 80 per cent of radiation forcing within the airspace. Dr Stettler said: “A really small proportion of flights are responsible for the vast majority of contrail climate impact, meaning we can focus our attention on them.”

Taking into account the congestion in the airspace above Japan, the team simulated these planes to fly either 2,000 feet higher or lower than their actual flight paths and found that the contrail climate forcing could be cut by 59 per cent by altering the altitudes of 1.7 per cent of flights.
