HAve since found out the emergency. It appears that one of the REx Metros' had an engine fire alarm go off. Said engine was shut down, and fire bottle discharged in flight.
From memory, the runways at PLC are 01/19 (sealed) 15/33, and 04/22 .... and have only been there once or twice, but have heard stories where the wind has been 270/45 , which still give a decent x-wind on EVERY strip.
Saab has x-wind component of 35kts, J31 is also 35kts, yet metro is (I believe) only 20 kts.
