Budapest diversion.
A classic opportunity for "order, counter-order, disorder".
imho its a poor decision to go back on a decision to divert. Once you've made a decision and committed, carry it through. It's tempting, I know, but. As it happens the result was completely benign but what if...what if...?
Looks awfully like more press-on-itis to me.
And it would be interesting to see if the scenario described above re cleared to land but field not open applied here too - I'll store that little gem away for BUD arrivals in future.
