In 1990, two friends Robert and Barry managed to survive the harsh conditions of the Sahara desert alone for two days. The two friends 1) had enrolled in the Marathon of the Sands, which was a seven-day foot race through the Sahara desert. Before the competition began they 2) had packed all the food, clothing and supplies they needed on their desert adventure in large rucksacks, which they carried on their backs. On the first day of the event the two friends 3) had been walking in the desert for a few hours when all of a sudden a sandstorm appeared out of nowhere. They had nowhere to take cover. Robert opened his rucksack only to realise that he 4) had forgotten to pack their compass. Terrified, the men sat in the middle of the sandstorm and waited for help to arrive. They 5) had been waiting for two days before the organisers of the event realised that the two men were missing.

В 1990 году два друга, Роберт и Барри, сумели в одиночку пережить суровые условия пустыни Сахара в течение двух дней. Они записались на «Марафон песков» — семидневную пешую гонку через Сахару. До начала соревнования они упаковали в большие рюкзаки всю необходимую еду, одежду и припасы. В первый день друзья несколько часов шли по пустыне, когда внезапно из ниоткуда появилась песчаная буря. Им негде было укрыться. Роберт открыл рюкзак и понял, что забыл упаковать компас. Испуганные мужчины сидели посреди песчаной бури и ждали помощи. Они ждали два дня, прежде чем организаторы соревнования поняли, что мужчины пропали.
