well assuming a more practical idea like the relief tubes of old (sorry to female pilots of the era), yesterday flew AC 007 from YVR to HKG and the map showed close flying to Kamchatka Peninsula.

Curious Russian response to empty wine bottles hurdling to ground at terminal velocity of around 200 kph and striking their Air Force bases - definitely reason for AC to stop using Canadian wine if label were to survive impact.

Sadly We don’t need another KE 007, so AC will need a better solution- with all due respect to your creative suggestion 😀
