 "Authority to so operate (International instrument flying) may be granted provided that two-way communication is maintained with ground stations."

The order of the ground station to No. 6 to attempt a landing at Kansas City was a violation of regulations since the ceiling at Kansas City at the time the order was issued was under the minimum permitted for landing at that airport, to wit: 700 feet.

Regulation applicable—Chapter 8, Sec. 7 (f)

"At the point cleared to, ceiling and visibility are steady or improving and not less than the authorized minimums for landing down through as specified in the approved section of the company's operations manual."
