Mode C veil is great and would be great to have in the London area to avoid all these poxy TCAS warnings that occur when spurious blips show up without altitude.
Also I remember time buidling in the US and we would fly instrument approaches at night and when reaching minima, click the approach lights on and hopefully the runway would light up in front of you...and not in somewhere completely different
Yeah.. the europeans really try hard to over-complicate aviation dont they?
