The LondonDerry trip Is a good example. Leaving Belfast the aircraft (737) descends towards LondonDerry OCAS, descends below FL100 OCAS prob IMC. This whole procedure is without RADAR. He then talks to LondonDerry ATC still without radar coverage and positions for a pilot interpretated procedure onto the ILS unless things have changed since I was last there 2 years ago? LondonDerry is not unique. There is a gliding club close by and it is quite feasable that some lost glider could be in the clouds with them.
