The way I see it, he wasn’t ‘blocked’ he just was not given preferential treatment.
My reason for thinking this is as follows:
There were thousands queueing for days at the gates. They would be let in in batches, processed, and then put immediately onto a military flight. The flights were coming in and out on a rapid 45min turnaround. They would land, be loaded with whoever and however many had been processed at that point, and leave. There was no room for waiting for people or delay. Rapid 45min in and out.
Then you have Pen, and his private plane. His plane would have to land and wait for him - potentially disruptive for the military planes doing their 45min turnarounds but that’s not the main issue for me.
For me the main issue is that Pen was demanding to be able to walk past all the queueing people (who may well have no clue who he was, no understanding that he wasn’t going to be taking ‘their seats’, and who were equally desperate for their lives), walk straight in at the front of the queue with three trucks of dogs and cats. (Potential for riots and unrest at this point anyone?)
Then he would have required processing, staff and animals. So staff processing the other days long queue would have to stop that, in order to process Pens people. Remember, the military planes aren’t waiting for people, they take whoever is ready at the time. Delays in processing mean you may well miss the flight, and the closer to the last day, the higher the chance that would be your ONLY flight.
And then you have to slot in his plane’s takeoff.
That’s how I see it. Now you can argue all you like about lack of gov organisation etc. But the reality is what it is at the time and people on the ground have to work with that they have not what they wish or should have had in ideal circumstances.
Pen was demanding to have his group prioritised, in a country in the midst of destroying itself, where there was real threat to the lives of many, not just him and his staff.
And I’m sorry, but in circumstances such as those, you should not get to buy your way to the front of the queue to get on your private plane when doing so will delay others without those means from being processed for their own escape.
