OTT is ‘Over The Top’. With Chester not being the busiest of places I look for overflights for a bit of spotting. With WAL (Walasey) being just 10 nm North of me I see plenty of interesting stuff that I tie up with ACARS, VHF and ADS-B.
Sometimes I get to see arrivals/ departures from Liverpool and occasional departures from Manchester (Monty/ Nokin departures).
