Can you help explain this?

Hey Guys,

Was surfing Airliners.net (http://www.airliners.net/) this evening and I came across this picture (http://www.airliners.net/open.file/399435/M/).

As the caption suggests, this doesn't appear normal.

Can anyone enlighten me on what exactly is happening here?

Thanks in advance!

Cheers,

Souls.

Looks like a failed start attempt of the APU?

I was guessing oil in the tailpipe following shutdown during taxi out.

Can we resolve whether this is taxi in or taxi out based on flap position and runway vs taxiway position?

Do they still allow smoking on VASP flights ..... could be the outflow valve opening.

Looks like no ignition to me :confused:
It could be oil smoke though. Short answer: Takeoff flaps and smoke not normal :}

Seems obvious to me. You guys too lazy to zoom in?
