What you discussed in that thread had many riders and a lot of confusion.
Imagine you are flying a commercial jet from A to B, flight time is 1h15m, A is your also your destination alternate and both airports are single runway only and weather is cavok on both airports.
Due to long taxi on the ground, you have burned more fuel than expected and once airbone you only have 5 min extra fuel
Since you mentioned an alternate, it is an IFR flight plan with alternate required. Then it requires usual fuel A to B+Cont+ to C+30min hold. You couldn't burn that during taxiing. There is an exception of not requiring a destination alternate in IFR but it has two conditions i.e. VMC approach and landing is possible
and the destination has two runways. Since your destination has only one runway you cannot file an IFR flight plan. So I take it as a VFR flight plan which requires fuel A to B + 30min . If you discover after take off that you have only 5min extra then you simply land back. You would avoid everything that can happen at destination. Five minutes fuel is nothing by the time you reach there you may not have even that. Now coming to our thread, a President of a country should definitely be treated as more valuable than half a ton of vegetables. For heaven's sake you can't take law in your hand and do whatever you feel like.
