Whiskey Tango (Foxtrot) Baltimore
This design features a unique representation of a Baltimore City character!
The Baltimore Police Department's aviation unit's Eurocopter EC 120 helicopters are frequently referred to as "Foxtrot" due to the tail marking. This name lends itself to the phonetic alphabet variation of WTF: Whiskey Tango Foxtrot. As in, "WTF is happening that's causing Foxtrot to shine a spotlight on my house?" or "WTF are the BPD up to in the sky right now?"
