The closest cobbled together online translation of the caption from Czech I could obtain is "A supersonic high-velocity aircraft (M = 3) study with a capacity of 500 passengers from the BAC company", which obviously does not make any real engineering sense in the peculiar combination of basic design parameters to begin with (or make any mention of the use of LH2 as a fuel for that matter), let alone in conjunction with a massively non Whitcomb design. Perhaps hesham can check whether that particular edition of Letectvi + Kosmonautika came out around April 1st, 1978...?
