contamination receive specific periodic training that will illustrate what contamination looks like and feels like on a wing and the amount of contamination that is detectable under different light conditions". They also ordered "airlines to establish a way to inform fight crews of the type of [deicing] fluid and mixture used, the current moisture accumulation rate, and the available holdover time." With regard to the obstructions with which the airplane collided during the accident sequence, the NTSB ordered the modification or replacement of "all pump houses adjacent to Runway 13/31 so that they are not obstructions to airplanes". They also ordered a study on the "feasibility of building a frangible ILS antenna array for LaGuardia Airport" Further, they ordered a review of Fokker F28-4000 passenger-safety briefing cards "to ensure that they clearly and accurately depict the operation of the two types of forward cabin doors in both their normal and emergency modes and that they describe clearly and accurately how to remove the over-wing emergency exit and cover." Dryden report allegations The crash was featured on National Geographic Channel in an episode of the television program Mayday (Air Crash Investigation/Air Emergency) entitled Cold Case, where the accident was compared with Air Ontario Flight 1363, which crashed in Dryden, Ontario, after the crew did not deice their jet. The program opened by saying that Canadian investigators were "stunned" to hear of the USAir accident, as it mirrored the Air Ontario flight that had occurred three years earlier. The report on the crash in Dryden criticized approaches to deicing. It made several points, including recommending the use of type II deicing fluid rather than type I, deicing trucks near the runway rather than at the gate, and that the crew should inspect their wings not only from the cockpit, but also the cabin. The report concluded that competitive pressures caused by commercial deregulation cut into safety standards, and that many of the industry's sloppy practices and questionable procedures were placing pilots in difficult situations. The Honourable Virgil P. Moshansky, who investigated the crash in Dryden and wrote the report, appeared in the documentary, alleging that if the recommendations in his report had been followed, the USAir accident could have been prevented. Moshansky told the documentary that his report "probably sat on somebody's [at the FAA] desk." He said, "when I first heard about it, I thought, my God, it's Dryden all over
