Default A disturbing statistic

Yes, also, reported that they were in the middle of the
river, not near the upwind shore.

| Probably. But even at that airspeed (112 mph), if they'd
turned with a
| 60-degree bank, they'd have had room to spare even if the
crosswind

would have been
| 975', and the turn would have taken 10 seconds, adding
500' of drift; the

both
