Worst air combat fiascos

what in your opinion have been the worst air combat fiascos in the post WWII era. Here’s my list:

1. Israel’s treacherous (but well executed) pre-emptive strikes against Arab airfields in 1967. 400 odd planes destroyed for a loss of 30 odd.

2. India’s attempts to destroy the small contingent of PAF Sabres in East Pakistan. Despite being outnumbered 200 to 14, the PAF planes shot down 40 IAF jets for 6 losses. ONly when the airfield was under threat of being overrun by tanks did the PAF itself destroy its planes.

3. Vietnam- despite supposed technological superiority, US could not do a thing. Lost over 2000 planes and a humiliating defeat.

4. Afghanistan- vaunted USSR air force was devastated by PAF- losing 30 planes without one kill.
