RIAT Sun 19 – MIG29 Polish A F – What was theheavy black smoke was before take off

RIAT Sun 19 July.

On Sat 18 I saw the Polish A F MIG 29 display but wasn’t close to the runway to watch it prior to take off and actullay take off.

On Sun 19 July prior to take off the Polish MIG29 was pouring out very heavy black smoke from the engine exhaust many times prior to moving on to the runway and then again just prior to rolling for take off.

Anyone know if this is normal routine?

Also everyone around me heard the commentator say that the same MIG29 was being flown without any FBW. Wow is all I can say.:cool:
