Liquid dripping from 777 wing
On a recent flight from LAX, passengers observed liquid dripping down the lowered flaps between the pylons of the starboard wing of 777-300.
The liquid formed a 1 meter wide band of steady drips until takeoff.
A rough estimate of 2 liters a minute for 15 minutes.
It was noticed by passengers seated in rear section, after pushback on an evening departure, humidity was around 65%.
No other moisture was visible on the airframe.
Cabin crew informed flight crew who strolled down the aisle and had a look for themselves, they later informed passengers that it was condensation.
Cabin crew had not seen the effect before.
A freak set of weather circumstances?
