ate wala po kayong where did the first catholic mass takes place in the philippines?

Im a commercial pilot instructor. Any pilot, sailor or traveler on cars too knows all vehicles need to have the maps or charts of the route to follow not only one and the others "follow me". What about if the ship or vehicle in front loose the others in a storm or simply at night? The others, with no maps or idea where they were going will get lost. Magellan didnt want to share the maps of the voyage. It is one of the rules of fleet or multi vehicle navigation. Magellan didnt give any maps of the route to the others ships, only the Portugese crew one in which he was too. That is a huge violation of navigation rules. Im a pilot instructor. He lied to the others about giving them the maps after a while, but didnt. Huge Magellan Devilish Plan to make the others get lost and he and the Italians and portugeese navigate only and put down Spain sailors. He wanted the Spain crews to get lost, of course. That is why the others mutiny againts him. The liar also become a murderer of spanish sailors that revelled due his devilish plans. His arrogance made him try to defeat about 1,000 islanders with only about 50. The liar arrogant got killed and Delcano decided to circumnavigate instead of backtrack which was the initial plan of Magellan, which also lied about the size of the pacific ocean.
