United Airlines Emergency Landing in Boston (ATC Conversations)

On April 23rd, new, a United Airlines Airbus A320 operating flight 224 from Chicago to Boston was on approach to runway 22L at Logan airport when most of its navigation systems failed, followed by a loss of pressurization. The pilots declared emergency and looked for alternate airports: with none nearby with visual meteorological conditions, and with some systems back in working order, the pilots followed the ILS glideslope and then landed visually. Job well done.\r
