How long did it take to set up those metal runways? Were the metal sheets spiked into the ground? How big were they? Also, how are commercial runways built?

  • $\begingroup$ What are you talking about? What "portable runway" are you asking about? Where was it built? When? $\endgroup$ – Ron Beyer Nov 13 '19 at 1:41

    $\begingroup$ Which runways? That might help us answer the rest of your questions. $\endgroup$ – Camille Goudeseune Nov 13 '19 at 2:29
  • $\begingroup$ It really depends on "where". $\endgroup$ – user3528438 Nov 13 '19 at 2:50

Google is your friend. Try it. "perforated metal airstrip"

"A runway two hundred feet wide and 5000 feet (1500 m) long could be created within two days by a small team of engineers."
