I got caught back in the 70s doing flood relief in a Huey around Charleville, QLD. The land is dead flat, so when a flood comes, the water spreads in sheets that can be 10-20 miles wide, meaning the pilot cannot see dry land anywhere from low level. Cloud prevents you from climbing. Maps mean nothing, because the only navigation features like roads, railways and rivers, are all under the water. And a Huey (ours, anyway) only has a single ADF for navigation.
We were tasked to go to station A to drop food, station B to collect a person to go to hospital, C for a mail drop, ooops, there is a new call to go to D to collect a pregnant lady who is about to pop, who knows that place? You do? OK, point the way. Time passes, no, that's not it... maybe that's it over there... no, over there...Land in the shallow water next to this house and ask them - damn, it is 5 miles back that way! Eventually we find the right farm, collect the lady and turn for Charleville on the NDB. No real idea where we are, just a general feeling that it is over there and not far away.
The fuel gauge is dropping, but there is no dry land to put it down on, no road that a fuel truck could use to get to us, the pregnant lady looks like she is bulging enough to burst, so on we go, following that single needle. The 20 minute fuel light had been on for about 10 minutes when we touched down on the airfield, the only piece of dry land around the town.
As this thread is called, what would YOU have done?
