Question Mark Vapor Trail

Not my photo, but it shows what I saw while on deck, but did not get a photo of. When a plane went to full throttle, the low pressure at the inlet formed this odd question mark-shaped vapor trail from the bottom of the inlet to the deck. It was very spooky - making it obvious how much air was flowing. It was not a place you wanted to get any closer to!!
