mmflynn: there is absolutely no way at this time that I will have adversarial dialogue with you over this terrible accident.The airspace issues @CVT/DSA are well documented within my company(note,not other airfields)and despite everybody's best efforts the worst case scenario has happened.It could only be worse in terms of scale if a commercial airliner was involved.I do not know why 'sad for all involved' needs to be quoted but it manifestly is.Out.
