Tuesday 10/22/24 ~1300Z / 0900AM ET - two pairs of UH60 Blackhawks (PAT01+flight, PAT03+flight) departing Pentagon northbound 10 minutes apart, took an unusual route through Zone 5 (Arlington VA area) west of the Potomac river close to the Rwy 19 arrival corridor, at about 700-800ft. Tower provided notifications of helicopter activity to incoming traffic and visual separation clearances to PAT, but this apparently triggered RA's and go-arounds for 3 flights (AAL2426, AAL220 and RPA4385).
1254Z PAT01+flight lifted Pentagon
1257Z AAL2426 go-around from 1275ft
1305Z PAT03+flight lifted Pentagon
1307Z AAL220 go-around from 1200ft
1309Z RPA4385 go-around from 1625ft (PAT03 ~1000ft)
(Altitudes per FlightAware / ADSB-Exchange).
Recordings edited for content to remove other transmissions, but left in realtime. Combination of DCA Tower and DCA Helicopter archives. Departure also had to deal with two go-arounds ("whoa whoa"), bringing AAL220 back to Final behind RPA4385.
