Space events
of the past.
Komarov's accident with the failure of the Soyuz 1 main parachute to deploy correctly.
(Sven's website is very good!).
And the Sun or Moon eclipse (depending on where you are looking it from) as seen from Surveyor 3 took place exactly the same day! (Surveyor 3 had landed only 4 Earth days before).
April 24 1967.
