Taily,
BB-415 was a laughable event. Made even more perplexing as the aircraft was fitted with an after market fuel computer, Shadin from memory?, and digital fuel flow gauges with low warning lights incorporated. An extra four flashing lights added to the standard B200 suite.
I joined the GFU just after the gliding event. the late WG spent some time explaining to me that he could not understand how this happened. He clearly remembered giving instructions for the aircraft to be refueled....
The God he prayed to, was not on the same page ....
