Ref post #6 – Akrotiri Lightning ejection
The IWIs were always reminding adventurous (and some daft) fighter pilots to fly a descending "S" curve into the firing position on the banner.
Clearly a low angle off was hairy for the towing pilot, but a climbing approach made the firing aircraft vulnerable to a banner coming off. Keeping a flight profile above the banner horizontal datum mitigated any collision probability and allowed a shot off banner to pass below the firing aircraft - as seen in many exciting gun camera frames.
Please tell us more about the Charlie Chan Akrotiri ejection – and the BOI – if there was one.
