Beags , the first Comet to drop out of the sky was actually G-ALYV climbing out of Calcutta May 2 with the loss of 43 Lives. 2 May 1953.
Coincidentally this was the registration chosen for the " Dinky Toys" toy Comet which went on to be sold well into the late 50's without change. ( Obviously no
PR queens in those days)
You will recall that these events were preceded by Comets going "through the hedge" on take -off, due to not being able to accelerate to flying speed if the nose was held too high ( leading to the adoption of drooped leading edges).
