grenade_helicopter is a model entity available in 
Half-Life 2 series. It's a time-bomb dropped by npc_helicopter.
The timer is only activated when the bomb comes in contact with the world geometry, or any props. If You manage to catch one by pressing +use on it before it touches the ground, you'll be able to hold unarmed, until you touch it against anything.
Upon touching an NPC or most other props it will detonate immediately. The bombs are also buoyant.
Note:In the HL2 Episodes, these bombs have double velocity when launched by the gravity gun. They will also delay the timer when picked up with the gravity gun, so that they can be aimed.Keyvalues
