He's never arriving Nigeria today with that Presidential jet. Rather that plane will circle the tarmac & the pilot will just quietly turn off engine.
Buhari is a very clever man to run away for his health. Because the poison killing him is inside Nigeria air space & if he breathe the air for anywhere in naija, he'll get worse or even soon die.
To avoid another yaradua scenario..him better stay away & be doing "long distance president"
